ABSTRACT:
A memory access request signal is generated with activation of three different signals, i.e., memory select signal, operating mode signal and operating input signal. When only the memory select signal and operating mode signal are activated, internal operation is not executed, and only an operating mode for determining access allow signal generation timing is determined. The access allow signal is generated at the same timing as the execution of the operating mode.
