MEMORY MANAGEMENT SYSTEM, METHOD, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a memory management system, method, and computer program for managing output data from a memory device storing raw data and error correction coding (ECC) bits.SOLUTION: A system includes; a controller configured to receive a read command and control a memory device based on the read command, where the memory device is configured to store raw data and error correction coding (ECC) bits and output the raw data and the ECC bits corresponding to memory addresses specified in the read command; and an ECC decoder configured to output an error vector associated with the memory addresses based on the raw data and the ECC bits corresponding to the memory addresses output by the memory device, the error vector associated with the memory addresses being indicative of errors in the raw data corresponding with the memory addresses. The system also includes a multiplexer (MUX) configured to output the error vector based on a selection indicated in the read command.SELECTED DRAWING: Figure 1
