A semiconductor integrated circuit so configured to stop the supplying of an electric power to a logic circuit in a standby mode, thereby to realize a low power consumption, includes a latch circuit characterized in that as the control signal a clock signal is supplied in the active mode, and a signal for creating an information hold condition is supplied in the standby mode, and in that MOSFETs applied with a control signal include a first conductivity type MOSFET having a high threshold and a second conductivity type MOSFET having a low threshold, a voltage amplitude of the control signal being larger than a power supply voltage. The semiconductor integrated circuit can be realized in that the high speed operation in the active mode and the low power consumption in the standby mode are compatible with each other, and it is sufficient if a power switch for the logic circuit is inserted at only either of the high level power supply voltage line side and the low level power supply voltage line side. In addition, the control signals are very few, and a fine timing control for changing over the mode is no longer required.

A latch type sense amplifier circuit comprises first and second latch circuits which output the same output signals when a potential difference between a bit line pair is equal to or greater than a predetermined value. The first and second latch circuits output different output signals when the potential difference between the bit line pair is less than the predetermined value. The latch type sense amplifier circuit further comprises a comparison result signal generating circuit which compares the output signals from the first and second latch circuits and outputs a signal indicative of the comparison result.

Mode switching transistors are inserted between the low-threshold logic circuit and VSS, between low-threshold input section and VCC and between the low-threshold input section and VSS, for effecting a sleep mode of the semiconductor integrated circuit. Low power dissipation is maintained with a reduced circuit scale.
