MEMORY SYSTEM INCLUDING RANDOMIZER AND DE-RANDOMIZER

摘要

A memory system according to an embodiment of the present invention may include a semiconductor memory device including a plurality of memory areas, and a controller suitable for writing data to the semiconductor memory device and reading data from the semiconductor memory device. The controller provides a combined seed, which is used to copy data in a first memory area to a second memory area, to the semiconductor memory device, the combined seed being obtained by performing an operation on a de-randomizing seed corresponding to the first memory area and a randomizing seed corresponding to the second memory area.
