TEMPERATURE-AWARE DATA MANAGEMENT IN MEMORY SUB-SYSTEMS

Abstract:

At least one source physical memory block stored in a memory device is identified. The source physical memory block comprises at least one logical unit. A determination is made as to whether an age characteristic of the logical unit satisfies a threshold criterion. A storage classification is determined for the logical unit based on whether the age characteristic of the logical unit satisfies the threshold criterion. The classification comprises a hot data classification or a cold data classification. A target physical memory block is identified based on the storage classification determined for the logical unit, and the logical unit is stored in the identified target physical memory block.
