PROBLEM TO BE SOLVED: To reliably reset the inner circuits of a semiconductor memory by controlling them from the outside. SOLUTION: The register section of the mode register includes two or more operation set-up sections to set up various operation specifications to drive the semiconductor memory. The mode register outputs soft reset signals when at least 1 bit of the register section shows a reset state. A reset signal generator circuit outputs reset signals to reset the inner circuits in response to the reset signals. The system to control the semiconductor memory is required to surely specify predetermined bits and the command to set up the mode register to generate soft reset signals. Thus, the inner circuits is surely reset by the outside control. COPYRIGHT: (C)2006,JPO&NCIPI
