[May 24, 2013] Spansion Assigned Patent Tweet (Targeted News Service Via Acquire Media NewsEdge) By Targeted News Service ALEXANDRIA, Va., May 24 -- Spansion, Sunnyvale, Calif., has been assigned a patent (8,445,972) developed by Yoshiharu Watanabe, Aizuwakamatsu, Japan, for a "semiconductor device with reconfigurable logic." The abstract of the patent published by the U.S. Patent and Trademark Office states: "A semiconductor device includes multiple transistors (70, 75, 80, 85), each of the transistors (70, 75, 80, 85) including a gate electrode (18) formed above a semiconductor substrate (30), source/drain regions (10, 12, 14, 16) formed on both sides of the gate electrode (18), and a charge storage layer (38) interposed between the gate electrode (18) and the semiconductor substrate (30). One of the source/drain regions (10, 12, 14, 16) of adjacent transistors (70, 75, 80, 85) is respectively connected in series, so the above-mentioned multiple transistors (70, 75, 80, 85) form a closed loop in the semiconductor device. Accordingly, it is possible to provide a semiconductor device (60) in which the circuit function of the logic circuit (64) can be reconfigured in a non-volatile manner, thereby enabling wide selectivity and excellent design facility in terms of the circuit design and making it possible to readily fabricate the logic circuit (64) and a non-volatile memory (62) on a single chip (60)." The patent application was filed on March 31, 2006 (11/394,515).
