Publication number: 20080218233Abstract: A clock input circuit 13 receives power during standby mode and comprises a NAND circuit NAND0 that controls a clock signal CK using a standby mode signal RET. When the standby mode signal RET is at a low level (in standby mode) clock signals C01 and C02 are kept at a high level and low level respectively regardless of the level of the clock signal CK. Further, power continues to be supplied to an FA section in the clock input circuit 13 and to an FB section in a slave latch circuit 12 whereas the power supply to the other circuits is shut off. As a result, the clock signals C01 and C02 remain at the high level and low level respectively and data is held by a loop formed by an on-state transfer gate circuit TG4 and activated inverter circuits INV5 and INV6 in the slave latch circuit 12.Type: ApplicationFiled: March 4, 2008Publication date: September 11, 2008Applicant: NEC ELECTRONICS CORPORATIONInventors: Hiroshi Yamamoto, Makoto Nonaka
