A memory system includes a memory device including a plurality of blocks, a buffer storing degradation information regarding at least one of the plurality of blocks, and a memory controller configured to determine a degradation level of the block corresponding to the read request based on the degradation information, in response to a read request from a host, infer a read level corresponding to the read request based on the degradation level, and read data from the memory device based on the read level.

Memory system processing request based on inference and operating method of the same

A storage device includes a non-volatile memory including a plurality of blocks, a buffer memory that stores a plurality of on-cell counts, which are generated by reading memory cells connected to a plurality of reference word lines of the plurality of blocks by using a read level, and an artificial neural network model, and a controller that inputs an on-cell count corresponding to a target block among the plurality of on-cell counts and a number of a target word line of the target block to the artificial neural network model, and infers a plurality of read levels for reading data of memory cells connected to the target word line using the artificial neural network model.
