CACHE ARRAY WITH REDUCED POWER CONSUMPTION

摘要

Embodiments of the disclosure include a cache array having a plurality of cache sets grouped into a plurality of subsets. The cache array also includes a read line configured to receive a read signal for the cache array and a set selection line configured to receive a set selection signal. The set selection signal indicates that the read signal corresponds to one of the plurality subsets of the cache array. The read line and the set selection line are operatively coupled to the plurality of cache sets and based on the set selection signal the subset that corresponds to the set selection signal is switched.

1. A method for reducing power consumption of a cache array having a plurality of cache sets, the method comprising:
receiving a read signal for the cache array; receiving a set selection signal indicating that the read signal corresponds to a subset of the plurality of cache sets of the cache array; and based on the set selection signal, reading only the cache sets of the subset of the cache array.
