Memory system, memory controller and method of operating same

Abstract

The disclosure provides a memory controller configured to control a memory device. The memory controller may include a map buffer, a descriptor queue, and a descriptor controller. The map buffer may sequentially store map segments of a plurality of map segments stored in the memory device. The descriptor queue may store descriptors corresponding to the respective map segments, based on a plurality of addresses of the map buffer. The descriptor controller may search for a target descriptor among the stored descriptors based on a logical address received from a host, and reorder the stored descriptors while searching for the target descriptor.

Background technique [0004] Typically, a storage device stores data under the control of a host device such as a computer or smartphone. The storage device may include: a memory device configured to store data; and a memory controller configured to control the memory device. In general, there are multiple types of memory devices: volatile memory devices and non-volatile memory devices. [0005] Volatile memory devices retain data only while power is supplied to them; data stored in them is lost when power is turned off. Example...
