Abstract
A memorystores a data block comprising a plurality of data values DV. An error code, such as an error correction code ECC, is associated with the memory and has a value dependent upon the plurality of data values which form the data block stored within the memory. If a partial write is performed on a data block, then the ECC information becomes invalid and is marked with an ECC_invalid flag. The intent is avoiding the need to read all data values to compute the ECC and thus save time and energy. The memory may be a cache linewithin a level 1 cache memory. Memory scrub control circuitryperforms periodic memory scrub operations which trigger flushing of partially written cache lines back to main memory.
