  • Fault correction apparatus for an address array of a store-in cache memory and method therefor
    Patent number: 5926484
    Abstract: When a fault is detected in data read-out from an address array, a replacement controller registers the address in a replacement buffer. When this address is sent out from the replacement buffer, the address array is invalidated for the address by using an address register and a flush register. During the invalidation process, the processing of the request is suppressed by a pending register, and the request address is held in an address register until the invalidation is completed for use in retrying a cache indexing.
