Memory controller performing booting operation and method of operating the same

Abstract

A memory controller includes a buffer, a prefetch controller, and a boot controller. The buffer stores workload information including a history of an expected I/O request expected to be received from a host during booting operation. The prefetch controller is configured to, before a target I/O request is received from the host after start of booting, read expected data corresponding to the expected I/O request from memory devices based on workload information, and store the expected data in the buffer. The boot controller updates the workload information based on the target I/O request depending on whether target data corresponding to the target I/O request is included in the expected data, and stores updated workload information in an area in which data is readable with a minimum number of accesses from a plurality of the memory devices.
