Abstract
Embodiments of the disclosed technology relate to a memory system, a memory controller, and an operation method of the memory system. According to embodiments of the present disclosure, the memory system may calculate a time period Tthat is between a beginning of a program operation on a memory page included in the memory device and a suspension of the program operation, may calculate a time period Tthat is between the suspension of the program operation and a time point that is before a resumption of the program operation, may calculate, based on the time period Tand the time period T, a read offset voltage to be applied to the memory cell to mitigate the change of the threshold voltage distribution, and may store the read offset voltage in the memory page in the memory device before the resumption of the program operation. Accordingly, the memory system is able to improve the reliability of operations of suspending and resuming a program operation and to improve the performance of a read operation.
