Discontinued Operations and Disposal Groups [Abstract]
LOSS FROM FOUNDRY PARTNERS	LOSS FROM EUROPEAN FOUNDRY ARRANGEMENTS In December 2008, Atmel and a subsidiary entered into a take-or-pay agreement to purchase wafers from a European foundry that had acquired one of its former European manufacturing operations. In connection with the anticipated expiration of this agreement, the Company notified customers, in the fourth quarter of 2012, of its end-of-life process and requested that customers provide to the Company last-time-buy orders. To the extent that the Company believes it has excess wafers that remain after satisfying anticipated customer demand, the Company estimated a probable loss for those excess wafers, which was approximately $10.6 million. The Company, therefore, recorded a charge in that amount to cost of revenue in the consolidated statements of operations for the year ended December 31, 2012. During 2013, the Company recognized a charge to cost of revenue of $7.4 million, which comprised a write-off of excess wafers in the amount of $10.4 million and a write-off of wafer prepayment in the amount of $1.9 million, which were partially offset by a reduction of a previously recorded liability from a take-or-pay arrangement for $4.9 million. These transactions resulted from the insolvencies of two of the Company's foundry suppliers. In June 2010, in connection with the sale of one of the Company's former European manufacturing operations, the Company leased facilities to the acquirer of those operations and has charged that acquirer rent and other occupancy costs. In the fourth quarter of 2012, the Company recorded a loss of $6.5 million on receivables from that tenant based on financial and other circumstances affecting the collectibility of those receivables, which is reflected under the caption of "impairment of receivables from foundry supplier" in the consolidated statements of operations for the year ended December 31, 2012.
