Abstract: The problem of bit disturb is reduced by discharging the floating bit lines of a nonvolatile memory array during programming. An illustrative virtual ground memory array uses single transistor floating gate type memory cells that are programmed using Fowler-Nordheim (“FN”) tunneling, highly conductive and lengthy bit lines, buried and relatively short sub-bit lines and a programming discharge circuit for controlling spurious voltages on the bit lines that can arise when some of the bit lines are left floating during programming. Discharge control transistor respectively coupled to the bit lines direct current into a discharge section. A discharge section may be provided for each bit line, or shared by all bit lines. The discharge section may be a fixed circuit section for use through the programming process or may be selected from multiple discharge options.

Abstract: An asymmetrical virtual ground single transistor floating gate memory cell has a floating gate that overlies a channel region in a p-well, the channel region lying between a heavily doped n+ drain region and a lightly doped n? source region. A heavily doped p+ region known as a “halo” is disposed in the channel adjacent the heavily doped n+ drain. The floating gate is spaced away from the channel region by a generally thin tunnel oxide. A lightly doped source with a graded source/channel junction reduces source side CHE generation. In one variation, a thicker oxide between the source and the floating gate reduces CHE injection from the source side. A heavily doped drain with a halo implant in the channel adjacent the drain enhances drain side CHE generation.

Abstract: In nonvolatile memory cell array, the memory cells of each sector are organized into groups of successive cells, the groups preferably being of the same size and preferably isolated from one another in both the row and column directions by a suitable isolation structure such as field dielectric or trench dielectric. Because of cell group isolation, each group of column lines may be decoded by its own relatively small program column select, which preferably is replicated in essentially identical form for all groups of column lines. While each program column select preferably is used to decode one group of column lines, larger program column selects may be used if desired to decode two or more groups of column lines. Read column selects may decode one or more groups of column lines as desired. The number of column lines decoded may the same as or different than the number of column lines decoded.

Abstract: An asymmetrical virtual ground single transistor floating gate memory cell has a floating gate that overlies a channel region in a p-well, the channel region lying between a heavily doped n+ drain region and a lightly doped n− source region. A heavily doped p+ region known as a “halo” is disposed in the channel adjacent the heavily doped n+ drain. The floating gate is spaced away from the channel region by a generally thin tunnel oxide. A lightly doped source with a graded source/channel junction reduces source side CHE generation. In one variation, a thicker oxide between the source and the floating gate reduces CHE injection from the source side. A heavily doped drain with a halo implant in the channel adjacent the drain enhances drain side CHE generation.

Abstract: A memory array contains memory cells designed to be erased using Fowler-Nordheim (“FN”) tunneling through the channel area, and programmed using either channel hot electron injection (“CHE”) or channel-initiated secondary electron injection (“CISEI”). To reduce disturbance of the floating gate potential of unselected memory cells during programming operations and read operations, the unselected word lines are brought to a negative potential rather than ground potential. To reduce disturbance of the floating gate potential of unselected memory cells during FN erase operations, the unselected word lines are brought to a positive potential rather than ground potential.
