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.

摘要： A nitride read only memory (NROM) cell can be programmed by applying a ramp voltage to the gate input, a constant voltage to one of the two source/drain regions, and a ground potential to the remaining source/drain region. In order to erase the NROM cell, a constant voltage is coupled to the gale input. A constant positive current is input to one of the source/drain regions. The remaining source/drain region is either allowed to float, is coupled to a ground potential, or is coupled to the first source/drain region.

摘要： A flash memory cell comprises a gate, a drain, a source, a floating gate, and a control gate. The flash memory cell is capable of being programmed by inducing a voltage drop of between about four volts and six volts across a deep-depletion region by applying a first voltage to the gate, a second voltage to the drain, and a third voltage to the source. During a programming operation, the channel current is approximately zero, and the first voltage is ramped at a rate proportional to the injection current.

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： A punch-through diode and method of fabricating the same are disclosed herein. The punch-through diode may be used as a steering element in a memory device having a reversible resistivity-switching element. For example, a memory cell may include a reversible resistivity-switching element in series with a punch-through diode. The punch-through diode allows bipolar operation of a cross-point memory array. The punch-through diode may have a symmetrical non-linear current/voltage relationship. The punch-through diode has a high current at high bias for selected cells and a low leakage current at low bias for unselected cells. In other words, the ratio of Ion/Ioff is high. Therefore, the punch-through diode is compatible with bipolar switching in cross-point memory arrays having resistive switching elements.
