    摘要: The device of the invention includes a plurality of isolation layers formed at predetermined regions of a semiconductor substrate and running parallel with each other. The devices of the present invention also include a high voltage PMOS placed on top of a deep N-well and NMOS placed above a triple P-well inside the deep N-well in the peripheral area to pass both positive and negative high voltage of around +20V and −20V to the cell area. In one embodiment, the cell array, source lines and bit lines are all placed on top of the P-substrate without a deep N-well or Triple P-well. In other embodiments, the cell array, source lines and bit lines are placed on top of the deep N-well and triple P-well.

    摘要: A combination EEPROM and Flash memory is described containing cells in which the stacked gate transistor of the Flash cell is used in conjunction with a select transistor to form an EEPROM cell. The select transistor is made sufficiently small so as to allow the EEPROM cells to accommodate the bit line pitch of the Flash cell, which facilitates combining the two memories into memory banks containing both cells. The EEPROM cells are erased by byte while the Flash cells erased by block. The small select transistor has a small channel length and width, which is compensated by increasing gate voltages on the select transistor and pre-charge bitline during CHE program operation.

    摘要: A nonvolatile memory array has a single transistor flash memory cell and a two transistor EEPROM memory cell which maybe integrated on the same substrate. The nonvolatile memory cell has a floating gate with a low coupling coefficient to permit a smaller memory cell. The floating gate placed over a tunneling insulation layer, the floating gate is aligned with edges of the source region and the drain region and having a width defined by a width of the edges of the source the drain. The floating gate and control gate have a relatively small coupling ratio of less than 50% to allow scaling of the nonvolatile memory cells. The nonvolatile memory cells are programmed with channel hot electron programming and erased with Fowler Nordheim tunneling at relatively high voltages.
