Abstract
A semiconductor memory device includes an address buffer, a clock buffer, a control signal buffer, a control circuit, a mode register, a memory cell array, a signal select circuit, a DLL, an I/O buffer and a QS buffer. The mode register provides a signal at H- or L-level to the signal select circuit. The signal select circuit selects a data strobe signal sent from an I/O terminal in accordance with the signal at L-level, and provides it to the QS buffer. The signal select circuit selects a clock sent from an I/O terminal in accordance with the signal at H-level, and provides it to the QS buffer.
