Programmable logic device and semiconductor device

摘要

Provided is a programmable logic device that includes logic elements arranged in a plurality of columns. Wirings connecting logic elements are arranged between the plurality of columns. Switch circuits that control electrical connections between the wirings and the logic elements are also arranged between the plurality of columns. Each of the switch circuit selects an electrical connection between one of the wirings and an input terminal of one of the logic elements in accordance with configuration data.
