Abstract
A programmable logic device comprises a data storage circuit for storing 1-bit control data and a MOS transistor which is switch controlled in accordance with stored data in the data storage circuit. When the MOS transistor is switch controlled, the power supply voltage of the data storage circuit is raised. Two signal lines are connected with each other through the MOS transistor which has been rendered conductive, thereby permitting a signal to be transmitted between the signal lines.
