SEMICONDUCTOR DEVICE

摘要

A programmable logic device (PLD) that can control whether to supply power in each logic element is provided. The PLD includes at least a programmable logic element, a terminal to which a potential is input from an external power source, a switch controlling conduction between the terminal and the logic element, and a memory outputting a control signal for setting the conduction state of the switch. The memory stores pieces of configuration data for setting the conduction state of the switch. Any one of the pieces of configuration data is output as the control signal from the memory to the switch.
