Abstract
The present technology includes a method of operating a controller that controls a semiconductor memory device including a plurality of memory blocks. The method includes receiving a read request for data included in any one memory block among the plurality of memory blocks from a host, and controlling the semiconductor memory device to read data corresponding to the read request using a read-history table. The read-history table includes read voltages used for a plurality of read pass operations for the any one memory block, respectively.
