Auto-increment write count for nonvolatile memory

Abstract:

A memory device has multiple nonvolatile (NV) memory arrays that collectively store a block of data, with each array to store a portion of the data block. A selected NV memory array stores a write count for the block of data. In response to a write command, the NV memory arrays that store data perform an internal pre-write read. The selected NV memory array that stores the write count will perform a pre-write read of the write count, increment the write count internally to the selected NV memory array, and write the incremented write count back to the selected NV memory array.
