Abstract

Provided are a semiconductor memory device, a memory system including the same, and an operating method thereof. The semiconductor memory device includes a memory cell array including a plurality of memory cells, a peripheral circuit suitable for reading least significant bit data and most significant bit data of neighboring memory cells adjacent to selected memory cells out of the plurality of memory cells, and generating pattern flag data using the least significant bit data and the most significant bit data and a control logic suitable for controlling the peripheral circuit to set a read voltage to be applied to the selected memory cells based on the pattern flag data.
