Abstract
A low-power programmable LSI that can perform dynamic configuration is provided. The programmable LSI includes a plurality of logic elements. The plurality of logic elements each include a configuration memory. Each of the plurality of logic elements performs different arithmetic processing and changes an electrical connection between the logic elements, in accordance with the configuration data stored in the configuration memory. The configuration memory includes a set of a volatile storage circuit and a nonvolatile storage circuit. The nonvolatile storage circuit includes a transistor whose channel is formed in an oxide semiconductor layer and a capacitor whose one of a pair of electrodes is electrically connected to a node that is set in a floating state when the transistor is turned off.
