Abstract

An associative cache memory for a computer with improved cache hit times. All possible data items are presented to bus driver circuits, thereby deferring data selection as long as possible. Driving and multiplexing are combined. The output of tag comparison directly selects at most one set of driver circuits. As a result, the only processing time in series with tag comparison is driver circuit selection. Since the data selection delay in series with tag comparison delay is reduced, the time delay is reduced for a clock edge for data driving after tag comparison, thereby enabling a faster clock.
