Abstract: A disturb management technique for a non-volatile memory including first and second memory cells includes programming the first memory cell by applying a first voltage to a first word line coupled to the first memory cell and a second voltage to a terminal, such as a source terminal, shared by the first memory cell and the second memory cell. A non-zero third voltage having the same sign as the second voltage is applied to a second word line coupled to the second memory cell. The applied non-zero third voltage reduces a tunnel current across a gate oxide that insulates the second word line from a substrate of the second memory cell. This results in the second memory cell having a lower likelihood of being disturbed when programming the first memory cell.

Abstract: In accordance with some examples, a system comprises a substrate layer having an outer surface. The system also comprises a plurality of trenches extending from the outer surface into the substrate layer. The system then comprises a plurality of active regions with each active region positioned between a different pair of consecutive trenches of the plurality of trenches. The system also comprises a dielectric layer disposed in each of the plurality of trenches and on each of the plurality of active regions. The system then comprises a gate layer disposed on the dielectric layer and extending at least partially into each of the plurality of trenches.

Abstract: A method is described for forming a memory structure using a hardmask (65). The hardmask (65) protects the second polysilicon layer (55) during a SAS etch process. In addition, sidewall structures (95) are formed which protect the inter-polysilicon dielectric layer (45) during the hardmask (65) etch process.

Abstract: A method for fabricating a semiconductor resistor in embedded FLASH memory applications is described. In the method a gate stack (54) is formed on an insulating region (70) of a semiconductor substrate. The control gate (20) is removed from the gate stack (54) and electric contacts (125), (130) are formed to contact the floating gate (16) to form the resistor.

Abstract: A structure and method for improving the sense margin of nonvolatile memories is disclosed. An improvement to the sense margin of nonvolatile memories is accomplished by improving the margin both for "ones" at low control gate voltage Vcc and for "zeros" at high control gate voltage Vcc. Improvement in sensing at low control gate voltages Vcc is accomplished by skewing the sense amplifier response characteristics by forming the channel length of the reference memory cell to have a longer channel length than the memory cells of the array.
