ABSTRACT:
In a semiconductor memory device wherein a difference in potential of two data buses is increased during a write mode and is reduced during a read mode, a write/restoring circuit is provided for carrying out a write operation which increases the difference in potential between the data buses and a restoring operation which reduces the increased difference in potential of the data buses to carry out a read operation after the write operation in accordance with a common write control signal using common output transistors.
