    摘要: A method and system to reduce the power consumption of a memory device. In one embodiment of the invention, the memory device is a N-way set-associative level one (L1) cache memory and there is logic coupled with the data cache memory to facilitate access to only part of the N-ways of the N-way set-associative L1 cache memory in response to a load instruction or a store instruction. By reducing the number of ways to access the N-way set-associative L1 cache memory for each load or store request, the power requirements of the N-way set-associative L1 cache memory is reduced in one embodiment of the invention. In one embodiment of the invention, when a prediction is made that the accesses to cache memory only requires the data arrays of the N-way set-associative L1 cache memory, the access to the fill buffers are deactivated or disabled.

    摘要: In one embodiment, a cache memory includes a data array having N ways and M sets and at least one fill buffer coupled to the data array, where the data array is segmented into multiple array portions such that only one of the portions is to be accessed to seek data for a memory request if the memory request is predicted to hit in the data array. Other embodiments are described and claimed.
