    摘要: A dummy memory cell for detection of write completion timing is provided as a replica of a memory cell. When assisting a write operation by power supply control and substrate potential control of the memory cell, the timing of ending the write assist operation is determined by a voltage control circuit based on information about the dummy memory cell. For example, the voltage control circuit performs, in a data write operation in the memory cell, the write assist operation of decreasing the voltage of a source power supply allocated to P-channel MOS load transistors using a pull-down transistor. Thereafter, at the time when completion of the data write operation in the dummy memory cell is detected, the voltage control circuit ends the write assist operation and restores the voltage of the source power supply to the original level using a pull-up transistor.

    摘要: An FM receiver which can be used by being switched between stereophonic and monophonic, and comprises detecting unit for detecting a received signal, two routes over which a detected signal is transmitted to an output buffer, and a switching unit for selecting either one of the two routes. The two routes consist of a route passing through a stereophonic demodulator unit and a route bypassing the stereophonic demodulator unit; and the switching unit selects either one of the two routes based on a control signal indicating the selection of either one of stereophonic and monophonic, and, when the route bypassing the stereophonic demodulator unit is selected, turns off power supply to the stereophonic demodulator unit based on the above control signal.

    摘要: An FM/AM switch (31) selects either an FM detected signal or an AM detected signal. A capacitor (4) is provided to cut the DC component of the FM detected signal. A low-cut frequency switch (33) selects a resistor designated by a control, signal from among resistors (Ra through Rc). A high-pass filter is constituted by the capacitor (4) and a resistor selected by the low-cut frequency switch (33). The cut-off frequency of this high-pass filter is adjusted by the selection of a resistor.
