摘要： According to an aspect of the embodiments, the block decoder control circuits which drive the pass transistors for the word lines for a flash memory array are driven with a control voltage that is regulated to be one enhancement transistors threshold voltage higher than the highest voltage that is actually driven onto the word lines. According to another aspect of some of the embodiments, the block decoder control circuits are implemented with transistors having a very low threshold voltage. According to yet another aspect of some of the embodiments, a special series connection is used to prevent any leakage current through the block decoder control circuit from the high voltage generating charge pumps which might otherwise result from the use of low threshold voltage transistors. In the special series connection, any leakage current occurs from the supply voltage source rather than from the high voltage generating charge pumps. According to still another aspect of some of the embodiments, a special gate connection applies an intermediate bias voltage higher than a positive supply voltage onto the gates of the unselected block decoder transistors that are connected to a high-voltage. Several embodiments are presented which combine the regulated control voltage aspect and various combinations of the other aspects.

摘要： A system and methodology is provided for programming first and second bits of a memory array of dual bit memory cells at a substantially high delta VT. The substantially higher VT assures that the memory array 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 of the memory cell causes the second bit to program harder and faster due to the shorter channel length. Therefore, the present invention employs selected gate and drain voltages and programming pulse widths during programming of the first and second bit that assures a controlled first bit VT and slows down programming of the second bit. Furthermore, the selected programming parameters keep the programming times short without degrading charge loss.
摘要翻译：提供了一种用于以基本上高的delta VT对双位存储器单元的存储器阵列的第一和第二位进行编程的系统和方法。基本上更高的VT确保存储器阵列将维持编程数据并且在相当长的一段时间内在较高的温度应力和/或客户操作之后一致地擦除数据。在基本上较高的增量VT下，存储器单元的第一位的编程使得第二位由于较短的通道长度而更硬更快地编程。因此，本发明在第一和第二位的编程期间采用选择的栅极和漏极电压以及编程脉冲宽度，以确保受控的第一位VT并减慢第二位的编程。此外，所选择的编程参数保持编程时间短而不降低电荷损耗。

摘要： An erase operation is performed on a non-volatile memory cell with an oxide-nitride-oxide structure by using a negative gate erase voltage during an erase procedure to improve the speed and performance of the non-volatile memory cell after many program-erase cycles. During the erase procedure, an erase cycle is applied followed by a read cycle until the cell has a threshold erased below a desired value. For the initial erase cycle in the procedure, an initial negative gate voltage is applied. In subsequent erase cycles, a sequentially decreasing negative gate voltage is applied until the threshold is reduced below the desired value. In one embodiment, after erase is complete, the last negative gate voltage value applied is stored in a separate memory. After a subsequent programming when the erase procedure is again applied, the initial negative gate voltage applied is the negative gate voltage value for the cell stored in memory.
摘要翻译：在擦除过程中通过使用负栅极擦除电压在具有氧化物 - 氮化物 - 氧化物结构的非易失性存储单元上执行擦除操作，以在许多编程擦除周期之后提高非易失性存储单元的速度和性能。在擦除过程期间，应用擦除周期，随后读取周期，直到单元具有低于期望值的阈值。对于程序中的初始擦除周期，施加初始负栅极电压。在随后的擦除周期中，施加顺序减小的负栅极电压，直到阈值降低到期望值以下。在一个实施例中，在擦除完成之后，施加的最后一个负栅极电压值被存储在单独的存储器中。在再次施加擦除过程之后的后续编程之后，施加的初始负栅极电压是存储在存储器中的单元的负栅极电压值。
