The Company and Summary of Significant Accounting Policies (Policies) | 6 Months Ended
--- | ---
Jun. 30, 2021
Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany transactions and balances have been eliminated in consolidation. The Company’s fiscal year ends on December 31 of each calendar year.
Risks and Uncertainties | Risks and Uncertainties The Company is subject to risks from, among other things, competition associated with the industry in general, other risks associated with financing, liquidity requirements, rapidly changing customer requirements, limited operating history and the volatility of public markets. COVID-19 The global outbreak of the coronavirus disease 2019 (COVID-19) was declared a pandemic by the World Health Organization and a national emergency by the U.S. government in March 2020. This has negatively affected the U.S. and global economy, disrupted global supply chains, significantly restricted travel and transportation, resulted in mandated closures and orders to “shelter-in-place” and created significant disruption of the financial markets. The full extent of the COVID-19 impact on the Company’s operational and financial performance will depend on future developments, including the duration and spread of the pandemic and related actions taken by U.S. and foreign government agencies to prevent disease spread, all of which are uncertain, out of the Company’s control, and cannot be predicted.
Use of Estimates | Use of Estimates The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses recognized during the reported period. Actual results could differ from those estimates.
Cash Equivalents and Investments | Cash Equivalents and Investments The Company has invested its excess cash in money market accounts, certificates of deposit, commercial paper, corporate debt, government-sponsored enterprise bonds and municipal bonds and considers all highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents. Investments with original maturities greater than three months and remaining maturities less than one year are classified as short-term investments. Investments with remaining maturities greater than one year are classified as long-term investments. Management generally determines the appropriate classification of securities at the time of purchase. All securities are classified as available-for-sale. The Company’s available-for-sale short-term investments are carried at fair value, with the unrealized holding gains and losses reported in accumulated other comprehensive income. Realized gains and losses and declines in the value judged to be other than temporary are included in the other income, net line item in the condensed consolidated statements of operations and comprehensive loss. The cost of securities sold is based on the specific identification method.
Fair Value Measurements | Fair Value Measurements The Company measures the fair value of financial instruments using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels: Level 1— Inputs used to measure fair value are unadjusted quoted prices that are available in active markets for the identical assets or liabilities as of the reporting date. Level 2— Pricing is provided by third party sources of market information obtained through the Company’s investment advisors, rather than models. The Company does not adjust for, or apply, any additional assumptions or estimates to the pricing information it receives from advisors. The Company’s Level 2 securities may include cash equivalents and available-for-sale securities, which consist primarily of certificates of deposit, corporate debt, and government agency and municipal debt securities from issuers with high-quality credit ratings. The Company’s investment advisors obtain pricing data from independent sources, such as Standard & Poor’s, Bloomberg and Interactive Data Corporation, and rely on comparable pricing of other securities because the Level 2 securities are not actively traded and have fewer observable transactions. The Company considers this the most reliable information available for the valuation of the securities. Level 3— Unobservable inputs that are supported by little or no market activity and reflect the use of significant management judgment are used to measure fair value. These values are generally determined using pricing models for which the assumptions utilize management’s estimates of market participant assumptions. The determination of fair value for Level 3 investments and other financial instruments involves the most management judgment and subjectivity.
Allowance for Doubtful Accounts | Allowance for Doubtful Accounts The Company establishes an allowance for doubtful accounts to ensure that its trade receivables balances are not overstated due to uncollectibility. The Company performs ongoing customer credit evaluations within the context of the industry in which it operates and generally does not require collateral from its customers. A specific allowance of up to 100% of the invoice value is provided for any problematic customer balances. Delinquent account balances are written off after management has determined that the likelihood of collection is remote. The Company grants credit only to customers deemed creditworthy in the judgment of management. The allowance for doubtful accounts was $41,000 at June 30, 2021 and December 31, 2020.
Inventories | Inventories The Company values its inventories at the lower of cost, which approximates actual cost on a first-in, first-out basis, or net realizable value. The Company records inventory reserves for estimated obsolescence or unmarketable inventories based upon assumptions about future demand and market conditions. Once a reserve is established, it is maintained until the product to which it relates is sold or otherwise disposed of. If actual market conditions are less favorable than those expected by management, additional adjustment to inventory valuation may be required. Charges for obsolete and slow-moving inventories are recorded based upon an analysis of specific identification of obsolete inventory items and quantification of slow moving inventory items. The Company recorded no material write-downs of inventory during the six months ended June 3 0, 202 1 and recorded write-downs of $0.1 m illion for the year ended December 31, 2020.
Revenue Recognition | Revenue Recognition The Company generates revenue primarily from sales of IC products and licensing of its IP. Revenues are recognized when control is transferred to customers in amounts that reflect the consideration the Company expects to be entitled to receive in exchange for those goods. Revenue recognition is evaluated through the following five steps: (i) identification of the contract, or contracts, with a customer; (ii) identification of the performance obligations in the contract; (iii) determination of the transaction price; (iv) allocation of the transaction price to the performance obligations in the contract; and (v) recognition of revenue when or as a performance obligation is satisfied. IC products Revenue is recognized when performance obligations under the terms of a contract with a customer are satisfied. The majority of the Company’s contracts have a single performance obligation to transfer products. Accordingly, the Company recognizes revenue when title and risk of loss have been transferred to the customer, generally at the time of shipment of products. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products and is generally based upon a negotiated, formula, list or fixed price. The Company sells its products both directly to customers and through distributors generally under agreements with payment terms typically less than 60 days. Royalty and other The Company’s licensing contracts typically provide for royalties based on the licensee’s use of the Company’s memory technology in its currently shipping commercial products. The Company estimates its royalty revenue in the calendar quarter in which the licensee uses the licensed technology. Payments are generally received in the subsequent quarter. Contract liabilities – deferred revenue The Company’s contract liabilities consist of advance customer payments and deferred revenue. The Company classifies advance customer payments and deferred revenue as current or non-current based on the timing of when the Company expects to recognize revenue. During the six months ended June 30, 2021, the Company recognized no revenue that had been included in deferred revenue as of December 31, 2020. See Note 5 for disaggregation of revenue by geography.
Cost of Net Revenue | Cost of Net Revenue Cost of net revenue consists primarily of direct and indirect costs of IC product sales and engineering personnel costs directly related to maintenance and support services specified in licensing agreements. Maintenance and support typically include engineering support to assist in the commencement of production of a licensee’s products.
Warrants | Warrants As of June 30, 2021, the Company had the following warrants outstanding (share amounts in thousands):
Type |  | Number of Shares |  |  | Exercise Price |  |  | Expiration
Common stock |  |  | 33 |  |  | $ | 47.00 |  |  | January 2023
Common stock |  |  | 106 |  |  | $ | 2.40 |  |  | October 2023
Per Share Amounts | Per Share Amounts Basic net income (loss) per share is computed by dividing net income (loss) for the period by the weighted-average number of shares of common stock outstanding during the period. Diluted net income (loss) per share gives effect to all potentially dilutive shares of common stock outstanding during the period. Potentially dilutive shares of common stock consist of incremental shares of common stock issuable upon the exercise of stock options, vesting of stock awards and shares issuable in conjunction with convertible notes. The following table sets forth securities outstanding that were excluded from the computation of diluted net loss per share as their inclusion would be anti-dilutive (in thousands):

|  | 2021 |  |  | 2020 |
Options outstanding to purchase common stock |  |  | 159 |  |  |  | 161 |
Unvested restricted common stock units |  |  | 58 |  |  |  | 81 |
Convertible notes |  |  | — |  |  |  | 262 |
Warrants |  |  | 139 |  |  |  | 1,879 |
