摘要： A method of erasing memory cells in a flash memory device that recombines holes trapped in the tunnel oxide (after an erase operation) with electrons passing through the tunnel oxide is disclosed. The method uses an erase operation that over-erases all memory cells undergoing the erase operation. A cell healing operation is performed on the over-erased cells. The healing operation causes electrons to pass through the tunnel oxide and recombine with trapped holes. The recombination substantially reduces the trapped holes within the tunnel oxide without reducing the speed of the erase operation. Moreover, by reducing trapped holes, charge retention, overall performance and endurance of the flash memory cells are substantially increased.

摘要翻译： 公开了一种擦除闪存器件中的存储单元的方法，该闪速存储器件将通过隧道氧化物的电子重新捕获隧道氧化物中的空穴（在擦除操作之后）。 该方法使用擦除操作，擦除所有进行擦除操作的存储单元。 对过度消耗的细胞进行细胞愈合操作。 愈合操作使电子通过隧道氧化物并与被捕获的孔重组。 该复合基本上减少了隧道氧化物内的被捕获的孔，而不降低擦除操作的速度。 此外，通过减少捕获的空穴，闪存单元的电荷保持率，总体性能和耐久性显着增加。

摘要： Methods and devices are disclosed, such methods comprising applying a verify pass-through voltage to unselected select lines of the floating-gate memory array that is greater than a read pass-through voltage applied to the unselected select lines. Other methods involve utilizing a cell current for reading a value from one or more memory cells in program-verify operations that is lower than a cell current for reading value from one or more memory cells in read operations.

摘要： A selected word line that is coupled to a cell to be programmed is biased during a program operation. The unselected word lines are biased with a negative potential to reduce the cell leakage at programming bit line potential. A programming pulse is applied to the bit line coupled to the cell to be programmed. During verification, the unselected word lines are biased back to ground potential.
