Patent attributes
Disclosed herein are techniques for management of a non-volatile memory device. In one example, an integrated circuit comprises a cache device and a management controller. The cache device is configured to store a first mapping between logical addresses and physical addresses of a first memory, the first mapping being a subset of mapping between logical addresses and physical addresses of the first memory stored in a second memory, and an access count associated with each of the physical addresses of the first mapping. The management controller is configured to: maintain access statistics of the first memory based on the access counts stored in the cache device; and determine the mapping between logical addresses and physical addresses stored in the second memory based on the access statistics and predicted likelihoods of at least some of the logical addresses receiving an access operation.
