US 9,286,237 B2 · Memory imbalance prediction based cache management

Abstract

Embodiments of methods, apparatuses, and storage media for memory imbalance prediction-based cache memory management are disclosed herein. In one instance, the apparatus may include a memory controller associated with a memory having a plurality of storage units. The memory controller may include logic configured to determine whether the memory enters into an imbalance state based at least in part on a difference in numbers of pending access requests to different storage units, and cause an adjustment of replacement management of a cache memory, based at least in part on a result of the determination. Other embodiments may be described and/or claimed.

An apparatus comprising:

a memory controller associated with a memory having a plurality of storage units, the memory controller including logic to determine whether the memory enters into an imbalance state based at least in part on a difference in numbers of pending access requests to different storage units, and cause an adjustment of replacement management of cached data in a cache memory, based at least in part on a result of the determination, wherein in response to the cached data includes data corresponding to an individual access request, the memory controller is to provide the requested data from the cache memory and not forward the individual access request to the memory, and wherein the adjustment of replacement management includes a delay in the replacement of at least some of the cached data.

At least one non-transitory computing device-readable storage medium having executable instructions that, in response to execution by a memory controller, cause the memory controller to:

determine whether a memory enters into an imbalance state based at least in part on a difference in numbers of pending access requests to different storage units;
cause an adjustment of replacement management of cached data in a cache memory, based at least in part on a result of the determination;
and
provide data corresponding to an access request from the cache memory rather than the memory in response to the cached data includes the data corresponding to the access request, wherein the adjustment of replacement management includes a delay in the replacement of at least some of the cached data.
