ABSTRACT:
To obtain a semiconductor memory device capable of keeping the internal circuit in active state at all times, without increasing the power consumption during normal operation, and not increasing the number of pins. A burn-in clock generating circuit (1) receives an external clock CLK, a mode signal MODE, and an internal clock INTCLK to output a burn-in clock BICLK to a decoder (5). The burn-in clock BICLK becomes a signal equivalent to the internal clock INTCLK when the mode signal MODE is a fixed signal of H or L indicating normal operation, and becomes a fixed signal of H for indicating activation at all times when the mode signal MODE is a clock at half frequency of the external clock CLK.
