Abstract
A direct sensing type semiconductor memory device combines read and write data bus lines in order to conserve real estate. The memory device includes a bit line pair and a sense amplifier connected between the lines of the bit line pair, and a data line pair. A first transistor is connected between a first potential and one of the data lines of the data line pair, and a gate of the first transistor is connected to one of the bit lines of the bit line pair. A second transistor is connected between the first potential and the other one of the data lines, and its gate is connected to the other of the bit lines. A switch circuit is connected between the data line pair and the bit line pair and transfers data from the data line pair to the bit line pair in accordance with a potential difference between the data line pair and the bit line pair.
