ABSTRACT:
A semiconductor integrated circuit which operates with a single power source and has a high-tension circuit for generating a voltage higher than a power voltage and for logically processing is enabled to operate at a low power voltage by reducing the current consumed in the high-tension circuit. The semiconductor integrated circuit of the present invention comprises a block transistor 1, Vcc line circuit 2, Vpp line circuit 3 and gate potential varying circuit 4. Gate potential of the block transistor 1 is controlled by the gate potential varying circuit 4. The gate potential varying circuit 4 outputs a signal for controlling the gate potential of the block transistor 1.
