Title: RECONFIGURABLE SEMICONDUCTOR DEVICE
Abstract:
[Problem] To enable production with standard processes, to enable the use of memory cell units as a synchronous memory, and to eliminate the need for expensive semiconductor designing. [Solution] Provided is a semiconductor device comprising a plurality of logic units that constitute an array and that are connected to one another, wherein: each logic unit has a pair of first and second memory cell units; each of the first and second memory cell units operates as a logic element when truth table data configured to output, to a data line, a logic computation of input values specified by a plurality of addresses is written in, or operates as a connection element when truth table data configured to output an input value specified by a certain address to a data line connected to the address of another memory cell unit is written in; a sequential circuit that is in synchronization with a clock is provided after the first memory cell unit; and the logic unit has, for each pair of memory cell units, a selection unit that selectively outputs an address to the first or second memory cell unit in accordance with an operation switching signal.
