Abstract
A semiconductor memory device includes a memory cell array including a plurality of memory cell array blocks, a plurality of pairs of first data lines for transceiving data with corresponding memory cell array blocks, a plurality of column selection signal lines disposed in an orthogonal direction to the pairs of first data lines, and a plurality of pairs of second data lines to transceive data with corresponding pairs of first data lines of the pairs of first data lines. The memory cell array includes a signal interference compensator that shifts a voltage level of a second data line signal of one of the pair of second data lines interfered by a column selection signal line, to a voltage level of a first data line signal of other of the pair of second data lines not interfered so as to compensate for a signal interference.
