The apparatus includes a memory card, parity DRAM locatable on the memory card, logic for generating and checking parity bits and logic for the control of the generating, checking and storing parity bits. Also, in another embodiment, the apparatus adds error correction code to the memory card to provide error detection and correction code to systems lacking such capabilities.
