A memory system having a word-addressable memory and bit changing circuitry for changing or updating individual bits within the data words stored in the memory. The memory includes a primary memory and a copy memory. The copy memory stores duplicates of the data words stored in the primary memory. The bit changing circuitry receives a word having a bit to be changed from the copy memory and returns the word, including the changed bit, to both the primary memory and copy memory.
