CACHE MEMORY, ERROR CORRECTION CIRCUIT, AND PROCESSOR SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a cache memory and error correction circuit that can reduce overhead due to error correction processing.SOLUTION: A cache memory 1 includes: a cache memory unit that can be accessed in units of cache lines; and a redundant code storage unit that stores a first redundant code for performing error correction for each cache line data which is stored in the cache memory unit in units of cache lines and a second redundant code for performing error correction of part of each cache line data.
