Explanatory Note

This amendment to the Current Report on Form 8-K/A (the “Amendment”) is being filed to amend the Company’s Form 8-K originally filed on May 18, 2011 and to file the Foundry Amendment (as defined herein) as an exhibit hereto.

Item 1.01 Entry into a Material Definitive Agreement.

Amendment to Foundry Agreement. On May 16, 2011, Spansion entered into an amendment (the “Foundry Amendment”) to the Foundry Agreement, dated as of August 31, 2007, between Spansion and Semiconductor Manufacturing International Corporation (“SMIC”). Under the terms of the Foundry Amendment, Spansion will prepay to SMIC $50 million for future wafer purchases. The prepayment will be paid in three installments over the 12-month period following execution of the Foundry Amendment. The Foundry Amendment also extends SMIC’s manufacturing obligations under the Foundry Agreement by expanding Spansion’s 65 nanometer capacity, adding Spansion’s 45 nanometer Flash memory, and requiring

1

SMIC to provide certain minimum wafer production capacity for production of 65 nanometer and 45 nanometer wafers. In addition, if under certain conditions SMIC fails to meet its capacity requirements under the Foundry Amendment, SMIC may be required to refund to Spansion certain portions of the prepayment. In addition, SMIC may be required to refund to Spansion a $5 million fee upon the occurrence of certain business acquisitions, the termination of the Foundry Amendment, or other events more fully described therein.

A copy of the Foundry Amendment is attached as Exhibit 10.1 hereto, the terms of which are incorporated herein by reference. The foregoing description of the Foundry Amendment is qualified in its entirety by reference to the full text thereof.
