Abstract
An NAND gate for outputting an output establishment detection signal in response to the fact that a complementary output of a latch type sense amplifier has been established is provided. When a tristate buffer is activated by signal, a word line which has been in a selected state is rendered non-selected state. Accordingly, current can be prevented from leaking from a power supply line to a ground line in tristate buffer. In addition, column current Ic flowing through memory cells can be minimized in response to the fact that word line has been set to a selected state.
