Abstract
An input/output circuit includes an I/O node connected to a pull up and pull down circuit having a pull up and pull down transistors. Data is sent and received at through the I/O node. A level shifter provides voltages including a supply voltage and a high voltage higher than the supply voltage. A signal control circuit controls the voltage level applied to the pull up and pull down circuit. During a data input mode, data is received at the I/O node and the pull up transistor is biased at the high voltage to cut off the pull up transistor. During a data output mode, data is output at the I/O node and the pull down transistor pulls down the I/O node to ground when the output data is low, and the pull up transistor is activated when the output data is high.
