A research group of Professor Hideo Ohno of Center for Spintronics Integrated Systems and Research Institute of Electrical Communication of Tohoku University together with NEC Corporation (NEC) developed a standby-power-free spintronics-based large-scale integrated circuit (LSI) using a nonvolatile magnetic tunnel junction (MTJ), a spintronic device. The developed LSI technologies are (1) fast access and high density nonvolatile core memory embedded in logic LSIs, (2) nonvolatile ternary content addressable memory (TCAM), (3) error correction circuits for highly reliable logic LSIs, (4) three-dimensional chip stack for nonvolatile logic LSIs, and (5) a reliable three-terminal spintronics device. They will be presented at the 2012 IEEE VLSI Symposia held at Honolulu, Hawaii on June 12-15, 2012.
