[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2020-0036676 filed on March 26, 2020, which is incorporated herein by reference in its entirety. technical field [0003] Various embodiments described herein relate to a memory controller and a method of operating the same. Background technique [0004] Various types of storage devices have been developed. Typically, these devices store data under the control of a computer, smartphone, or other host device, and are often equipped with a controller for performing data storage operations to the memory. [0005] The memory can be volatile memory or non-volatile memory. Volatile memory can store data only when powered. When the power is disconnected or interrupted, the stored data is lost. Examples of volatile memory include static random access memory (SRAM) and dynamic random access memory (DRAM). Non-volatile memory can maintain storage of data...
