Memory systems, operating methods and readable storage mediums

Abstract

Examples of the present application disclose a memory system, a method of operating the same and readable storage medium. The memory system includes: a memory device and a memory controller coupled with the memory device, wherein the memory controller is configured to: acquire operating temperatures of the memory device in time sequence, and determine an equivalent duration under a set temperature of a first duration for which the operating temperature lasts; accumulate the equivalent duration corresponding to the first duration; and control the memory device to perform dummy read operation in response to the accumulated equivalent duration being greater than or equal to a second duration; wherein the second duration is a time interval with which the memory device is triggered periodically to perform the dummy read operation under the set temperature.
