&#147;Report&#148;) of Rambus Inc. (&#147;we,&#148; &#147;Rambus&#148; or the &#147;Company&#148;) for the reporting period January&nbsp;1, 2016 to December&nbsp;31, 2016 (the &#147;Reporting Period&#148;) has been prepared in accordance with the
requirements of <FONT STYLE="white-space:nowrap">Rule&nbsp;13p-1</FONT> (the&nbsp;&#147;Rule&#148;) and Form SD promulgated under the Securities Exchange Act of 1934, as amended. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Rule requires disclosure of certain information when a company manufactures or contracts to manufacture products where the minerals specified in the Rule
are necessary to the functionality or production of those products. The specified minerals are referred to as &#147;Conflict Minerals,&#148; which include gold, columbite-tantalite (coltan), cassiterite, wolframite and their derivatives, which are
limited to tantalum, tin and tungsten. The &#147;Covered Countries&#148; for purposes of the Rule and this Report are the Democratic Republic of Congo (the &#147;DRC&#148;), or any adjoining country, including the Republic of Congo, the Central
African Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania, Zambia and Angola. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">This Report and Form SD can be found on our website at
www.investor.rambus.com. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Company Overview </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Rambus
creates innovative hardware and software technologies, driving advancements from the data center to the mobile edge. Our chips, customizable IP cores, patent licenses, software, services, and other innovations improve the competitive advantage of
our customers. We collaborate with the industry, partnering with leading ASIC and SoC designers, foundries, IP developers, processor companies, EDA companies and validation labs. Our innovations are integrated into a wide range of devices and
systems, powering and securing diverse applications, including Big Data, Internet of Things, mobile, consumer and media platforms. While we have historically focused our efforts on the development of technologies for memory, SerDes and other chip
interfaces, we have expanded our portfolio of inventions and solutions to address chip and system security, mobile payments and smart ticketing. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">During
the Reporting Period we began to ship our first physical semiconductor products. Currently, we offer DDR2, DDR3 and DDR4 chipsets for RDIMM and LRDIMM server modules that support the data center and enterprise server infrastructure markets. We
operate a fabless business model and use third-party foundries and assembly and test manufacturing contractors to manufacture, assemble and test our semiconductor products. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Description of the Company&#146;s Conflict Minerals Policy </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our goal is to eliminate the use of Conflict Minerals. We are aware that our chipsets contain tin, tantalum, tungsten and gold (&#147;3TG&#148;) metals that
are necessary to the functionality or production of those products. To this end, Rambus works with its chipset suppliers to identify the sources of all 3TG&nbsp;metals used in our chipsets. If any of these metals originate from the Covered
Countries, then further investigation is required. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We use the tools provided by the Conflict-Free Sourcing Initiative (&#147;CFSI&#148;) to gather
information from our suppliers. The information requested includes the name and location of smelters or refiners used to produce the metals, and the origin of the minerals. Our due diligence process and efforts are consistent with the Organisation
for Economic Co-operation and Development (&#147;OECD&#148;) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas (&#147;OECD&nbsp;Guidance&#148;). </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Our Conflict Minerals Policy can be found on our website at <I>www.investor.rambus.com</I>. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Description of the Company&#146;s Supply Chain </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Because we operate a fabless business model, we do not directly purchase 3TG from mines, smelters, or refiners. Therefore, we must rely on our suppliers to
provide information regarding the country of origin of Conflict Minerals that are included in the Covered Products (as defined below). Many of our suppliers do not purchase raw materials directly and must rely on their downstream suppliers and
sub-suppliers to determine the origin of their raw materials. Thus, reliably determining the origin is a difficult task, and our suppliers are highly dependent on the information provided to them by their suppliers and sub-suppliers which are often
far removed from the direct smelter or refiner. Additionally, many of our suppliers are not directly subject to the same conflict minerals law and regulations as we are. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Identification of Conflict Minerals and of the Company&#146;s Products Covered by this Report </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We sent a questionnaire to our operating business units inquiring whether during the Reporting Period any of our units manufactured or contracted to
manufacture any products containing Conflict Minerals necessary to such products&#146; functionality or production. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Based on these inquiries, we
determined that our chipsets were the only products that met this test (&#147;Covered Products&#148;). We found that Conflict Minerals were not necessary to the functionality or production of any product that we manufactured or contracted to
manufacture other than the Covered Products that we contracted to manufacture during the Reporting Period. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">From this information, we developed a list of
direct suppliers within our chipset supply chain to be surveyed and who provided 3TG materials for our products. Engineering and evaluation materials were not included in our analysis. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Description of the Company&#146;s Reasonable Country of Origin Inquiry </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We conducted in good faith a reasonable country of origin inquiry (&#147;RCOI&#148;) with respect to the Covered Products that were manufactured or contracted
to be manufactured by us during the Reporting Period. The RCOI is reasonably designed to determine if any of the Conflict Minerals in the Covered Products originated in the Covered Countries and whether any of the Conflict Minerals may be from
recycled or scrap sources. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Once we identified our list of suppliers, we began the process of surveying the supply chain using the CFSI&#146;s Conflict
Minerals Reporting Template (&#147;CMRT&#148;). The CMRT is used predominantly throughout the electronics industry and requests relevant information, including details of the smelters and refiners where the materials were processed and the location
of mines where the minerals originated. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We informed each identified supplier of our desire to use only materials verified to be conflict-free and asked

the necessary information about the source of Conflict Minerals contained in the Covered Products that we contract with them to manufacture for us. Our suppliers are similarly reliant upon information provided by their suppliers to provide
information regarding the country of origin of Conflict Minerals that are included in the Covered Products. Thus, there is a risk that the final information provided to us and upon which we rely is incomplete or inaccurate. </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Because we do not have direct relationships with suppliers of the 3TG materials, we rely upon third parties to perform audits and certify smelters/refiners as
conflict-free. The Conflict-Free Smelter Program coordinates audits of 3TG smelters/refiners and publishes lists of those that are found to be conflict-free by following OECD Guidelines. The CFSI also publishes names of smelters/refiners that are
actively in the process of becoming certified conflict-free, but have not completed the process to date. Rambus uses these published lists to determine if the smelters and refiners supplying 3TG materials for our Covered Products are conflict-free.
If the sources of all 3TG materials for a product have been identified as conflict-free, then Rambus likewise considers such product as <FONT STYLE="white-space:nowrap">conflict-free.</FONT> </P>

<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We report on our due diligence efforts as required by law. We publicly filed the Form SD and this Report with the SEC. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">This Report includes information about the RCOI we undertook, our due diligence process designed to conform with the OECD Guidelines, the list of known
smelters and refiners utilized in our supply chain identified in our due diligence process, and a description of our products that incorporate Conflict Minerals necessary to the functionality or production of such products. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Findings and Conclusions </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">During the Reporting Period, we
utilized four suppliers with respect to our chipset products and required all of these suppliers to perform and report on their supply chain due diligence through the use of the CMRT. We received a 100% response rate to our requests. Responses from
our suppliers using the CMRT have been reviewed, combined and summarized. Responding parties provided a CMRT which includes a declaration page and a list of smelter and refiner names. Based on the information provided to us by our suppliers, we
believe that, to the extent reasonably determinable, the facilities that were used to process the Conflict Minerals contained in the Covered Products included the smelters and refiners listed in Annex I below. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">All suppliers provided complete lists of smelters representing 100% of the 3TG materials they utilized. Two suppliers declared that a portion of the 3TG
metals came from the Covered Countries. However, these suppliers also indicated that such materials came from a smelter or refiner that has been audited and is listed as conflict-free and compliant by the CFSI. One supplier declared that they are
uncertain if any 3TG materials came from the Covered Countries. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We combined the responses from all suppliers and prepared a list of unique smelter or
refiner names. We then used the CFSI compliance lists to determine if the Conflict Minerals originate from the Covered Countries and could be benefitting armed groups. All of the smelters/refiners on our list have been verified as compliant by CFSP.
Therefore, based on our due diligence efforts, we conclude the Conflict Minerals contained in our Covered Products come from suppliers using smelters or refiners listed as compliant by CFSI. However, we rely on our direct suppliers to provide us
with the necessary information about the source of Conflict Minerals contained in the Covered Products that we contract with them to manufacture for us and our suppliers are similarly reliant upon information provided by their suppliers. Thus, there
is a risk that the final information provided to us and upon which we rely is incomplete or inaccurate. </P>

 <P STYLE="margin-top:0pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Future Steps to Improve Due Diligence </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">We have communicated our expectations to our contract manufacturers regarding our commitment to sourcing minerals for our products in a manner that does not
finance or benefit armed groups in the Covered Countries. We plan to continue our inquiry method and utilize the CMRT to collect and report on due diligence activities with our supply base. We continue to work with our suppliers to improve the
quality and completeness of information collected by using the most updated CMRT form. We will continue to review our supplier responses, provide feedback as necessary, encourage our suppliers to remain committed to conflict-free sources and engage
with our relevant suppliers in order to build their knowledge and capacity so they are able to provide us with complete and accurate information on the source and chain of custody of Conflict Minerals in our supply chain. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Conclusion </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Based on our due diligence efforts and
subject to the limitations of such efforts as detailed above, we conclude the Conflict Minerals contained in our Covered Products come from suppliers using smelters or refiners listed as compliant by CFSI. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Additional Risk Factors </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The statements above are based
on the RCOI process and due diligence performed in good faith by Rambus. These statements are based on the infrastructure and information available at the time. A number of factors could introduce errors or otherwise affect our Conflict Minerals
status. These factors include, but are not limited to, gaps in supplier data, gaps in smelter data, errors or omissions by suppliers, errors or omissions by smelters, the definition of a smelter not being finalized at the end of the 2016 reporting
period, all instances of Conflict Minerals necessary to the functionality or manufacturing of our products possibly not yet having been identified, gaps in supplier education and knowledge, timeliness of data, public information not discovered
during a reasonable search, errors in public data, language barriers and translation, supplier and smelter unfamiliarity with the protocol, oversights or errors in conflict free smelter audits, Covered Countries sourced materials being declared
secondary materials, companies going out of business, certification programs being not equally advanced for all industry segments and metals, and smuggling of Conflict Minerals from the Covered Countries to countries beyond the Covered Countries.
</P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Forward-looking Statements </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">This Conflict Minerals
Report contains forward-looking statements. These statements include statements regarding steps we intend to examine to further mitigate risk. We also use words such as &#147;believe,&#148; &#147;expect,&#148; &#147;future,&#148; &#147;intend&#148;
and similar expressions to identify forward-looking statements.&nbsp;All forward-looking statements involve risk and uncertainty. When considering these statements, you should also consider the important factors described in this Conflict Minerals
Report under the heading &#147;Additional Risk Factors&#148; and in the reports and documents we file from time to time with the SEC, including the factors described under the sections titled &#147;Risk Factors&#148; in our most recently submitted
Annual and Quarterly Reports on Forms 10-K and 10-Q, respectively. Except as required by law, we disclaim any obligation to update information contained in these forward-looking statements whether as a result of new information, future events, or
otherwise. </P>
