Semiconductor memory device
Abstract:
According to one embodiment, a semiconductor memory device includes a plurality of memory cells each of which is arranged at the intersection position between a pair of complementary bit lines and a word line, and stores data between a first power supply voltage applied to a first node and a voltage applied to a virtual ground node, and a control circuit which changes the amount of current of the pair of bit lines in accordance with the amplitude of the pair of bit lines for each column in a memory macro, that is formed by arranging the plurality of memory cells in a matrix, in the data read operation of each of the plurality of memory cells.
