Abstract
There is provided a high-performance semiconductor integrated circuit whose circuit area is small and whose wiring length is short. The semiconductor integrated circuit is constructed in a multi-layer structure and is provided with a switch block for switching connections among a plurality of signal lines by means of a plurality of transistors formed respectively in a plurality of semiconductor layers and a plurality of logic blocks formed in each of the plurality of semiconductor layers and connected to each of the plurality of signal lines. The first switch block is a programmable switch block capable of changing the connection topology among the plurality of signal lines.
