Segment Reporting [Abstract] |
Segment and Other Information | Segment and Other Information Segment information reported herein is consistent with how it is reviewed and evaluated by our chief operating decision maker. We have the following four business units, which are our reportable segments: Compute and Networking Business Unit (“CNBU”): Includes memory products and solutions sold into client, cloud server, enterprise, graphics, and networking markets. Mobile Business Unit (“MBU”): Includes memory and storage products sold into smartphone and other mobile-device markets. Embedded Business Unit (“EBU”): Includes memory and storage products and solutions sold into automotive, industrial, and consumer markets. Storage Business Unit (“SBU”): Includes SSDs and component-level solutions sold into enterprise and cloud, client, and consumer storage markets. Certain operating expenses directly associated with the activities of a specific segment are charged to that segment. Other indirect operating income and expenses are generally allocated to segments based on their respective percentage of cost of goods sold or forecasted wafer production. We do not identify or report internally our assets (other than goodwill) or capital expenditures by segment, nor do we allocate gains and losses from equity method investments, interest, other non-operating income or expense items, or taxes to segments.
