    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: 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: Floating-gate field-effect transistors or memory cells formed in isolated wells are useful in the fabrication of non-volatile memory arrays and devices. A column of such floating-gate memory cells are associated with a well containing the source/drain regions for each memory cell in the column. These wells are isolated from source/drain regions of other columns of the array. Fowler-Nordheim tunneling can be used to program and erase such floating-gate memory cells either on an individual basis or on a bulk or block basis.
