Abstract
A memory system includes a nonvolatile memory device including a plurality of memory cells; and a controller including a control unit and a random-access memory, and configured to determine, by applying a program verify voltage to at least one memory cell to be programmed with program data, whether the program data is programmed, wherein the control unit determines percentages of a count of read requests received from a host device and a count of program requests received from the host device, and adjusts a level of the program verify voltage based on the percentages.

A memory controller comprising:
- a control unit configured to generate a command based on a difference between a frequency of a read request and a frequency of a write request for a set time;
- and
- a memory interface unit configured to transmit the command including control signals to a memory device.
