    摘要: A semiconductor integrated circuit device including an I/O circuitry capable of low-voltage high-speed operation at low cost is provided. In the I/O circuitry, when an I/O voltage (for example, 3.3 V) is lowered to a predetermined voltage (for example, 1.8 V), portions causing a speed deterioration are a level conversion unit and a pre-buffer unit for driving a main large-sized buffer. In view of this, a high voltage is applied to a level up converter and a pre-buffer circuit. By doing so, it is possible to achieve an I/O circuitry capable of low-voltage high-speed operation at low cost.

    摘要: The present invention provides a semiconductor integrated circuit having two kinds of input/output circuits realizing higher speed and higher packing density with rational configuration. The semiconductor integrated circuit has a first input/output circuit operating on a first power source voltage, an internal circuit operating on a second power source voltage lower than the first power source voltage, and a second input/output circuit operating on a third power source voltage lower than the first power source voltage. In an output circuit of the first input/output circuit, signal amplitude corresponding to the second power source voltage is converted to signal amplitude corresponding to the first power source voltage by a level shifter, and a P-channel MOSFET and an N-channel MOSFET constructing the output circuit are driven. In an output circuit of the second input/output circuit, a drive signal is generated by a level shifter in a manner similar to the above to drive second and third N-channel MOSFETs for generating an output signal having signal amplitude corresponding to the third power source voltage.
