1. A method of memory access, comprising:

  • comparing a memory error count for a retrieved block of non-volatile memory to a threshold error value, the threshold error value based on an Error Correcting Code (ECC) capability of the non-volatile memory; and

    assigning an error value to the retrieved block based on the comparison of the threshold error value and transferring the assigned error value if the memory error count exceeds the threshold error value, the threshold error value indicative of a maximum number of correctable errors per block of the non-volatile memory, the assigned error value based on a host processor issuing a request for the retrieval.
