In some embodiments, a non-volatile cache memory may include a segmented non-volatile cache memory configured to be located between a system memory and a mass storage device of an electronic system and a controller coupled to the segmented non-volatile cache memory, wherein the controller is configured to control utilization of the segmented non-volatile cache memory. The segmented non-volatile cache memory may include a file cache segment, the file cache segment to store complete files in accordance with a file cache policy, and a block cache segment, the block cache segment to store one or more blocks of one or more files in accordance with a block cache policy, wherein the block cache policy is different from the file cache policy. The controller may be configured to utilize the file cache segment in accordance with information related to the block cache segment and to utilize the block cache segment in accordance with information related to the file cache segment. Other embodiments are disclosed and claimed.
