Abstract
A semiconductor memory device is capable of writing data in phase with external data to a memory cell regardless of which memory cell the data is written to. The semiconductor memory device includes a scrambler, a write selector and a read selector. The scrambler is configured to output a control signal activated when an address for accessing a memory cell of a complementary bit line is inputted. The write selector is configured to selectively transmit data of a write path in response to the control signal. The read selector is configured to selectively transmit data of a read path in response to the control signal.
