Granted: 2005-09-21
Abstract: On a sleep state, a voltage dropping circuit 2 supplies a power supply line VA1 with a voltage obtained by dropping a voltage of a power supply line VA2, instead of a voltage in accordance with ON state of a switch QA1. A power supply line GND has a voltage equal to the ground voltage. A charge pump circuit 10 outputs the ground voltage on an active state. The charge pump circuit 10 outputs a voltage which is lower than the ground voltage, on the sleep state. A source electrode and a substrate electrode are connected to the power supply lines VA1 and VA2 in each of pMOS transistors Q3 and Q4 of an internal circuit 1 (latch circuit), respectively. A source electrode is connected to the power supply line GND in each of nMOS transistors Q5 and Q6 of the internal circuit 1. A substrate electrode is supplied with the voltage which is outputted from the charge pump circuit, in each of the nMOS transistors Q5 and Q6 of the internal circuit 1. As a result, it is possible to reduce a leakage current with holding data in the internal circuit on the sleep state, even if the supply voltage drops on the sleep state.

IPC: H01L27/115
Filed: 2003-01-08
Granted: 2006-08-21
Abstract: A system and methodology is provided for programming first bit (C0, C2, C4, C6) and second bit (C1, C3, C5, C7) of a memory array (68) of dual bit memory cells (10, 82, 84, 86, 88) at a substantially high delta VT. The substantially higher VT assures that the memory array (68) will maintain programmed data and erase data consistently after higher temperature stresses and/or customer operation over substantial periods of time. At a substantially higher delta VT, programming of the first bit (CO, C2, C4, C6) of the memory cell (10, 82, 84, 86, 88) causes the second bit (C1, C3, C5, C7) to program harder and faster due to the shorter channel (8) length. Therefore, the present invention employs selected gate and drain voltages and programming pulse widths during programming of the first bit (C0, C2, C4, C6) and second bit (C1, C3, C5, C7) that assures a controlled first bit VT and slows down programming of the second bit (C1, C3, C5, C7). Furthermore, the selected programming parameters keep the programming times short without degrading charge loss.
