Abstract:
A memory controller managing a memory device receives a memory read command from a host device that is communicably coupled to the memory device. The memory device includes a storage memory comprising a first type of memory cells and a cache memory comprising a second type of memory cells. The memory controller determines, from the memory read command, a physical address of a target memory location in the storage memory indicated by the memory read command. The memory controller executes a read operation on the target memory location corresponding to the physical address. The memory controller determines a read attribute of the target memory location. Conditioned on determining that the read attribute satisfies one or more threshold conditions, the memory controller programs an entry in the cache memory with information corresponding to the target memory location.
