Memory system for processing a write request and migrating data in read-intensive state and operating method thereof

Abstract

Embodiments of the present disclosure relate to a memory system and an operating method thereof. According to embodiments of the present disclosure, a memory system may determine whether the memory system is in a read-intensive state; when determined that the memory system is in the read-intensive state, process a write request received from a host using at least one first type memory block among the plurality of memory blocks, and migrate data stored in a second type memory block to the at least one first type memory block; and set a number of bits that can be stored in a memory cell included in the first type memory block to be less than a number of bits that can be stored in a memory cell included in the second type memory block.
