ABSTRACT:
A data storage comprises memory having a plurality of memory cells operative to retain data until read. A buffer cooperates, under the control of an address and buffer manager, with the memory to receive data read from the memory cells of a plurality of memory blocks of the memory. Error correction logic is operatively configured to examine the data read from the memory blocks and determine and correct corrupt data thereof. After the data has been processed by the error correction logic, the address and buffer manager enables write circuitry to write-back the select blocks of memory cells with the processed data of the buffer.
