Abstract

A correct error correction code can be generated even if a RAM error occurs before writing store data in cache memory (RAM) after confirming that cache line data for storage includes no errors. Before writing the store data, cache line data for storage is stored in a register, the store data is written to the cache memory, the stored contents of the register are merged with the store data, and an error correction code is generated for a result of the merger.
