Abstract
Provided herein may be a memory controller and a method of operating the same. The memory controller may include a SPO detector configured to output a detection signal when a SPO is detected, a memory buffer configured to store host data, and a power loss controller configured to, based on the detection signal, receive dump data corresponding to the host data, store the dump data and a dump age corresponding to the dump data, and output the dump data and the dump age to a memory device, wherein the dump age indicates a number of times that different items of host data have been dumped from the memory buffer to the power loss controller, and the power loss controller is configured to control a recovery operation corresponding to the SPO based on the dump age being received from the memory device.
