ABSTRACT:
Modified CAMs are used to generate a reset signal to other redundant CAMs which provide decoding for accessing redundant memory. Because the redundant CAMs use a single UPROM, half-latch circuit, the redundant CAMs are capable of latching to the wrong logic state. Whenever signal conditions which can cause improper latch-up are present, at least one of the modified CAMs are affected due to their sensitivity. Then, the modified CAMs will generate a reset signal until the improper latch-up condition is removed.
