Abstract: L'invention permet de réduire la consommation d'une mémoire sans affecter sa vitesse de fonctionnement à l'aide d'un décodeur de lignes 5 à faible consommation. Le décodeur de lignes comporte des circuits de pilotage DL et des circuits de décodage 30 à 31. Les circuits de pilotage DL sont répartis en groupes. Chaque groupe de circuits de pilotage ayant son alimentation partiellement coupée par au moins un transistor supplémentaire 41 à 44 si aucun circuit de pilotage du groupe n'est sélectionné. L'alimentation est partiellement coupée afin de couper l'alimentation des transistors des circuits de pilotage présentant les fuites les plus importantes. La coupure d'alimentation partielle commute des courants peu importants et ne nécessite pas de précaution lors de la remise sous-tension.

Abstract: The memory cell (10) comprises two inverter circuits (14,16) interconnected between the data nodes (N1,N2) so to form a memory circuit (12), two programming transistors (28,30) for implementing an irreversible degradation of the gate oxide layers of transistors (18,18'), and two transistors (32,34) for implementing the functioning of the memory cell after programming. Each inverter circuit (14,16) comprises supplementary MOS transistors (18,20;18',20') connected in series between a supply voltage source (VDD) and the ground circuit (22). Each inverter circuit comprises a p-MOS transistor (18,18') and an n-MOS transistor (20,20'), and the data nodes (N1,N2) are formed between the two transistors, n-MOS and p-MOS. The degraded MOS transistor is a transistor with thin gate oxide layer (GO1). The oxide layer is degraded at least locally so to obtain a variation of current through the transistor at the time of reading the cell. The programming transistors (28,30), or the diodes, are connected between the programming control line (PROG) and the transistors of the inverter circuits. The n-MOS programming transistors (28,30) ensure a selective connection of the gates of the transistors (18,18') to a programming voltage (VREF) at a level sufficient to cause the degradation of the gate oxide layers of the transistors. The inverter circuits are interconnected by the intermediary of a n-MOS transistor (32,34) connected to the control line (SRAM) of functioning the cell as the SRAM cell. The drain and the source electrodes of the transistors (32,34) are connected to the gates of the transistors of the inverter circuits.

Abstract: The unit has a pair of cells (C1, C2) for storing two independent bits and including field effect transistors with grid (4, 14), respectively. A channel is arranged in a source zone (102), and the two transistors are arranged in between the source zone and a drain zone. An electrode of single polarization (24) is arranged between intermediate portions (1, 11) of the two transistors. An independent claim is also included for a method for manufacturing an integrated DRAM on a surface of a substrate.

Abstract: The method of memory cell read access control has a memory cell (CM) connected to a bit line (BL) and having a reference cell (DCMP) connected to a reference line (BLN). During the read phase the reference cell and secondary reference (DCMS) are connected to the bit line and after deactivating the reference cells precharging the bit line to a precharge voltage above or below the final voltage.
