ABSTRACT:
A method and system are for reducing power consumption in a multi-way set-associative cache memory. During a first clock cycle, in response to an address, an associated set is identified in the cache memory. The address is compared to respective tag portions of blocks in the associated set, and a signal is output in response thereto. During a second clock cycle, in response to the signal indicating a match between one of the blocks and the address, a non-tag portion of the matching block in the associated set is read, while a non-matching block in the associated set is disabled.
