摘要:
A memory array comprising transistors having isolated inter-gate dielectric regions with respect to one another. Transistors are formed such that each of the transistors in the array has a charge storage region such as a floating gate, a control gate and an inter-gate dielectric layer therebetween. The inter-gate dielectric layer for each transistor is isolated from the inter-gate dielectric of each of the other transistors in the array.

Multiple select gates in association with non-volatile memory cells are described. Various embodiments include multiple select gate structure, process, and operation and their applicability for memory devices, modules, and systems. In one embodiment a memory array is described. The memory array includes a number of select gates coupled in series to a number of non-volatile memory cells. A first select gate includes a control gate and a floating gate electrically connected together and a second select gate includes a control gate and a floating gate which are electrically separated by a dielectric layer.

Memory arrays and methods of operating such memory arrays are described as having a memory cell operated as a single level cell interposed between and coupled to a select gate and a memory cell operated as a multiple level memory cell. In some embodiments, a memory array is described as including a number of select gates coupled in series to a number of memory cells operated as single level memory cells and a number of memory cells operated as multiple level memory cells, where a first select gate is directly coupled to a first memory cell operated as a single level memory cell interposed between and coupled to the first select gate and a continuous number of memory cells operated as multiple level memory cells.

A transistor construction includes a first floating gate having a first conductive or semiconductive surface and a second floating gate having a second conductive or semiconductive surface. A dielectric region is circumferentially surrounded by the first surface. The region is configured to reduce capacitive coupling between the first and second surfaces. Another transistor construction includes a floating gate having a cavity extending completely through the floating gate from a first surface of the floating gate to an opposing second surface of the floating gate. The floating gate otherwise encloses the cavity, which is filled with at least one dielectric. A method includes closing an upper portion of an opening in insulator material with a gate material during the deposition before filling a lower portion with the gate material. The depositing and closing provide an enclosed cavity within the lower portion of the opening.

Various embodiments include methods, apparatus, and systems for reading an adjacent cell of a memory array in an electronic device to determine a threshold voltage value of the adjacent cell, the adjacent cell being adjacent a target cell, and reading the target cell of the memory array using a wordline voltage value based on the threshold voltage value of the adjacent cell. Additional apparatus, systems, and methods are described.
摘要:
In a non-volatile semiconductor memory device and a method for manufacturing the device, each memory cell and its select Tr have the same gate insulating film as a Vcc Tr. Further, the gate electrodes of a Vpp Tr and Vcc Tr are realized by the use of a first polysilicon layer. A material such as salicide or a metal, which differs from second polysilicon (which forms a control gate layer), may be provided on the first polysilicon layer. With the above features, a non-volatile semiconductor memory device can be manufactured by reduced steps and be operated at high speed in a reliable manner.

Embodiments of the present disclosure provide methods, devices, and systems for performing a programming operation on an array of non-volatile memory cells. One method includes programming a number of cells to a number of final data states. The method includes performing, prior to completion of, e.g., finishing, the programming operation, an erase state check on a subset of the number of cells, which were to be programmed to an erased state.

Methods, devices, modules, and systems for operating memory cells are taught. A method for operating memory cells includes programming at least one of the memory cells to one of a number of states. The method also includes programming at least another one of the memory cells, which is adjacent to the programmed at least one of the memory cells, to one of a different number of states. The method further includes sensing non-erased states of the memory cell's using at least one common voltage level.
摘要:
A memory device includes a memory array including a plurality of cells. The cells are divided into a plurality of subsets. Each subset has at least one associated trim parameter. The trim parameter for each subset is stored in the memory array within the associated subset. Circuitry is operable to program at least a portion of a selected subset using the associated trim parameter. A method for operating a memory device includes storing at least one trim parameter for each of a plurality of subsets of a memory array in the memory device within each of the subsets. At least a portion of a selected subset is programmed based on the at least one trim parameter associated with the selected subset.
