Abstract: 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.

Abstract: 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.
