Abstract
PURPOSE:To prevent a chip select access from being delayed from an address access, by obtaining an address transition detector signal, based on a control pulse signal at the time of the chip select access. CONSTITUTION:The titled device is provided with an inhibiting circuit 7 for inhibiting an output of a address transition detector ATD circuit 3 for a prescribed time at the time of variation of a chip select CS input signal, and a CS access control circuit 6 for sending out a control pulse signal consisting of a one-shot pulse at the time of variation of the CS input signal, so that an ATD signal can be obtained, based on the control pulse signal at the time of CS access. In such a way, the ATD signal of the same timing as that which is obtained at the time of variation of an address input signal is obtained by the CS access control circuit at the time of variation of the CS input signal, therefore, it can be prevented that the CS access is delayed against an address access.
