Abstract:
A semiconductor integrated circuit, comprising:first and second power supply terminals;a first transistor connected to said first power supply terminal and coupled in series between said first and second power supply terminals, said first transistor having a first threshold voltage;logic circuitry performing a logic function, said logic circuitry connected between said first transistor and said second power supply terminal and comprising a plurality of transistors having a second threshold voltage lower than said first threshold voltage;control circuitry generating at least one control signal defining when said first transistor is to be operated in a non-conducting state and said logic circuitry is to be in a standby state; andvoltage generating circuitry coupled to said control circuitry and responsive to said at least one control signal for generating a first control voltage which is greater in absolute value than a first standard power supply voltage and of a polarity which when applied to said first transistor renders said first transistor non-conductive, said voltage generating circuitry supplying said first control voltage to said first transistor to render the first transistor non-conductive.
