Method, apparatus, and system to enhance negative voltage switching
Abstract:
The present invention is in the field of flash memory. More particularly, embodiments of the present invention may provide a negative voltage for erasing when coupled to a memory cell to be erased and provide voltages to read or program when not coupled to a memory cell that is selected to be erased. Embodiments may also provide a high magnitude negative voltage to erase; a low impedance, low voltage current to read or program; and burn little to no current when not coupled to a memory cell that is selected to be erased.
Abstract(Chinese):

本发明在闪速存储器领域。 更具体地说，本发明的实施例可以在耦合到待擦除的存储器单元时提供用于擦除的负电压，并且当未耦合到被选择要擦除的存储器单元时提供读取或编程的电压。 实施例还可以提供高幅度的负电压来擦除; 低阻抗，低电压电流读取或编程; 并且当不耦合到被选择被擦除的存储器单元时，几乎没有电流消耗。
