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, and does ECC on each byte of a data word, Thus, individual bytes of multiple data words can be written without the need for read-modify-write cycles. Hence, additional or dynamically changeable wait states need not be present in the system. Therefore, the SIMM is usable on a great number of different computer systems without modification.
