A semiconductor device capable of reconfiguration, including: a plurality of logic units which configure an array and are connected to each other, wherein each logic unit includes a pair of a first and a second memory cell units, each of the first and the second memory cell units operates as a logic element when truth value table data is written in, which is configured so that a logic calculation of an input value specified by a plurality of addresses is output to a data line, and/or operates as a connection element when truth value table data is written in, which is configured so that an input value specified by a certain address is output to a data line to be connected to an address of another memory cell unit, a latter stage of the first memory cell unit includes a sequential circuit which synchronizes with a clock, and the logic units include, for each pair of the first and the second memory cell units, a selection unit which selectively outputs an address to the first or the second memory cell unit in accordance with an operation switch signal.

Reconfigurable semiconductor device

A reconfigurable semiconductor device includes a plurality of logic units connected to each other via address lines or data lines, each of the logic units including: a plurality of address lines; a plurality of data lines; a first address decoder that decodes addresses inputted from some of the address lines; a second address decoder that decodes addresses inputted from the other of the address lines; a first memory cell unit having a plurality of memory cells and selecting, among said plurality of memory cells, a predetermined number of memory cells in accordance with the address decoded by the first address decoder; and a second memory cell unit having a plurality of memory cells and selecting, among said plurality of memory cells, a predetermined number of memory cells in accordance with the address decoded by the second address decoder.
