Divestiture	Dec. 31, 2023
Discontinued Operations and Disposal Groups [Abstract]
Divestiture	Divestiture In July 2023, the Company entered into an asset purchase agreement (the “Purchase Agreement”) with Cadence Design Systems, Inc. (the “Purchaser”), pursuant to which the Company agreed to sell certain assets and the Purchaser agreed to assume certain liabilities from the Company, in each case with respect to the Company’s PHY IP group, for $110.0 million in cash, subject to certain adjustments and certain closing conditions (the “Transaction”). The decision to sell this business reflects the evolution of the Company’s core semiconductor business to focus on the development of digital IP and chips, including novel memory solutions for high-performance computing, to support the continued advancement of the data center and artificial intelligence. The Transaction was completed on September 6, 2023 and resulted in net proceeds of approximately $106.3 million, which consisted of the initial selling price of $110.0 million offset by approximately $3.7 million related to certain purchase price adjustments. The Company recognized a net gain on divestiture of the PHY IP group in its Consolidated Statements of Operations of approximately $90.8 million during the year ended December 31, 2023. Transaction costs of approximately $1.4 million were included in the net gain of $90.8 million. The divestiture of the PHY IP group did not represent a strategic shift that would have a major effect on the Company’s consolidated results of operations, and therefore its results of operations were not reported as discontinued operations. Concurrent with the Transaction, the Company also recorded a charge of approximately $10.0 million in the Company’s Consolidated Statements of Operations during the year ended December 31, 2023. The charge was primarily related to the accelerated amortization of software licenses that were not directly part of the PHY IP disposal group.
