A semiconductor integrated circuit includes a CMOS circuit for processing an input signal in an active mode, a control switch, and a control memory. The control switch supplies a pMOS body bias voltage and an nMOS body bias voltage to an N well in a pMOS transistor and a P well in an nMOS transistor, respectively, in the CMOS circuit. The control memory stores control information indicating whether or not the pMOS body bias voltage and the nMOS body bias voltage are supplied from the control switch to the N well in the pMOS transistor and the P well in the nMOS transistor, respectively, in the CMOS circuit in the active mode.

    摘要: A substrate bias technique is used in an active mode enabling a high yield, and an operating consumption power and the fluctuation of a signal delay in signal processing are reduced in the active mode. The additional PMOS and NMOS of the additional capacitance circuit are produced in the same production process as the PMOSs and the NMOSs of the CMOS circuits. The gate capacitance of the additional PMOS is coupled between the power supply wiring and the N well and the gate capacitance of the additional NMOS is coupled between the ground wiring and the P well. The noise on the power supply wiring is transmitted to the N well through the gate capacitance and the noise on the ground wiring is transmitted to the P well through the gate capacitance. The fluctuation of noise on the substrate bias voltage between the source and the well of PMOS and NMOS of the CMOS circuits is reduced.

    摘要: In this invention, high manufacturing yield is realized and variations in threshold voltage of each MOS transistor in a CMOS•SRAM is compensated. Body bias voltages are applied to wells for MOS transistors of each SRAM memory cell in any active mode of an information holding operation, a write operation and a read operation of an SRAM. The threshold voltages of PMOS and NMOS transistors of the SRAM are first measured. Control information is respectively programmed into control memories according to the results of determination. The levels of the body bias voltages are adjusted based on the programs so that variations in the threshold voltages of the MOS transistors of the CMOS•SRAM are controlled to a predetermined error span. A body bias voltage corresponding to a reverse body bias or an extremely shallow forward body bias is applied to a substrate for the MOS transistors with an operating voltage applied to the source of each MOS transistor.
