Patent number: 8634229Abstract: A memory cell is provided with a transistor which includes source and drain electrodes formed in a semiconductor film by respectively N-doped and P-doped areas. The transistor includes first and second devices for generating a potential barrier in the semiconductor film. The two potential barriers are shifted laterally and are opposed to the passage of the charge carriers emitted by the nearest source/drain electrode. One of the devices for generating the potential barrier is electrically connected to the gate. The other of the devices for generating the potential barrier is electrically connected to the counter-electrode. The writing of a high state is carried out by imposing on the P-doped electrode a potential higher than that of the N-doped electrode and charging the capacitor formed between the gate and the semiconductor film. The resetting of the memory cell is obtained by discharging the capacitor.Type: GrantFiled: October 22, 2012Date of Patent: January 21, 2014Assignees: Commissariat a l'Energie Atomique et aux Energies Alternatives, Centre National de Recherche ScientifiqueInventors: Jing Wan, Sorin Cristoloveanu, Cyrille Le Royer, Alexander Zaslavsky
