ABSTRACT:
Write switch signal output circuits for outputting write switch signals for controlling the turning-on/off of transfer gates for interconnecting digit lines and write data lines are supplied with a write enable signal that controls write timing and pairs of complementary write data signals outputted from write data output circuits. When the write data output circuits are inactive, the write switch signal output circuits inactivate the write switch signals because the paired complementary write data signals are of a precharged potential level. When the write data output circuits are active, the write switch signal output circuits activate the write switch signals when the write enable signal is active because write data is outputted as the paired complementary write data signals.
