Memory systems, operating methods, and readable storage mediums

Abstract

Examples of the present application disclose memory systems, methods of operating the same, and readable storage mediums. An example memory system includes a memory device and a memory controller coupled to the memory device. The memory controller is configured to: in response to a read command, determine a time period to which a time difference between writing and reading of data to be read corresponding to the read command belongs; determine an amount of the voltage shift according to the time period to which the time difference between the writing and reading of the data to be read belongs; and determine a read voltage for reading the data to be read based on the amount of the voltage shift and the default read voltage.
