ABSTRACT:
A SIMM is provided which adds ECC onto a computer system, which system does not have ECC capabilities. The SIMM has ECC on board. The SIMM also has logic to sense whether the system is an "even" parity or "odd" parity system. Parity of the written data bytes is checked, and check bits used for the ECC are manipulated to check parity on the read cycle responsive to the sensed parity of the system. During the read cycle, parity is generated by the logic corresponding to the sensed system parity, and ECC is performed.
