According to one embodiment, a semiconductor memory device includes a first cell array includes memory cells and reference cells, a second cell array located adjacent to the first cell array in a first direction, a third cell array located adjacent to the first cell array in a second direction crossing the first direction, a fourth cell array located adjacent to the second cell array in the second direction, and a sense amplifier connected to the first to fourth cell array and configured to compare a current through a memory cell with a current through a reference cell to determine the data of the memory cell. A reference cell is selected from a cell array which is diagonally opposite to a cell array as a read target. |
