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.

Abstract: A memory system, a memory controller and an operating method are disclosed. By dividing a read count table including read count values respectively for a plurality of memory blocks into one or more read count table segments each including one or more read count values of a resolution, and managing one or more flags respectively corresponding to the read count table segments, and set the flag corresponding to the read count table segment in which at least one read count value is changed among the read count table segments, it is possible to minimize additional operational costs required to recover the read count table upon occurrence of an SPO.

Abstract: A memory system includes a memory device including a first memory block used for power-loss data protection and a controller coupled to the memory device. The controller includes a hardware layer and a firmware layer. The hardware layer checks whether at least one write data entry belongs to a programmable range in the memory device after power loss occurs, determines whether a logical address associated with the at least one write data entry is repeated, and programs the at least one write data entry in the first memory block.

Abstract: A data storage device includes: a nonvolatile memory apparatus including a plurality of memory blocks allocated as first open blocks for purposes other than garbage collection and a controller. The controller is configured to allocate, among the first open blocks, an open block for garbage collection for performing a garbage collection operation when switching the nonvolatile memory apparatus to a garbage collection mode, and to copy data stored in valid pages of a victim block, to store the copied data into the open block for garbage collection, and to erase the victim block during the garbage collection operation, thereby securing a free block.
