    Reliability of SRAM with ECC


      My questions are regarding the CY7C1381KVE33 (flow through SRAM with ECC, 18Mbits):

      - What is the failure rate of the CY7C1381KVE33? Please confirm it takes into account the probability for the ECC function to fail.
      - Can Cypress provide a FMEDA (Failure Mode, Effect and Diagnostic Analysis)?
      - Can Cypress provide a factory test coverage rate?
      - Suppose that for some reason, the ECC mechanism fails in such a way that any stored data, even corrupted, is considered as good, and is consequenty NOT corrected.
      Is such a failure possible?
      - Is there any means for the application to check that the ECC function actually works?

      Thanks a lot,
