A 20ns-write 45ns-read and 10 14 -cycle endurance memory module composed of 60nm crystalline oxide semiconductor transistors

Development of LSI targeting artificial intelligence (AI) has accelerated, some chips have been used and are commercially available in a number of applications. LSI capable of performing arithmetic operation for deep learning, etc., at low power and high speed is crucial for achieving more sophisticated AI. Power consumption is increasing significantly owing particularly to the practical use of AI, and power reduction techniques are urgently necessary.
