Methods and devices for cache management

Abstract

In accordance with some embodiments of the present disclosure, a method for operating a storage device coupled to a host device includes the storage device receiving priority information from the host device identifying high priority data stored on the storage device. The high priority data is identified by the host device based on a user interface identification of the high priority data stored on the storage device, or a plurality of requests to access the storage device generated by at least one application executing on the host device. The method further includes identifying an idle period in which no requests from the host device are received by the storage device, and transferring, during the idle period, at least a portion of the high priority data from the first memory to the second memory.
