ABSTRACT:
A method of and apparatus for continuous parity checking within a CMOS SRAM memory system. Each cell has added circuitry which permits continuous reading of the binary state of the cell. The states of each cell are combined to produce a parity determination for a given data array. By continuously monitoring parity in this manner, the time of failure as well as the fact of failure can be determined.
