Abstract
PURPOSE:To shorten time until the inverted signal of an internal address is fixed, and to shorten access time more by constituting a circuit, not necessitating a clocked inverter. CONSTITUTION:A second switching means, which allows an external address signal of the output of a first switching means to pass through it only when the external address signal ext Ai is necessitated, and a third switching means, which allows the internal address signal Qi of the output of an internal address generating device to pass through it only when the external address signal ext Ai is not necessitated and in addition, the internal address signal Qi is necessitated, are provided. Accordingly, because the output of a latch circuit means can be fixed faster, a storing means can be accessed with shorter address hold time and within shorter access time. Thus, the semiconductor memory device with faster operating speed is obtained.
