    摘要: The present invention presents a scheme for sensing memory cells. Selected memory cells are discharged through their channels to ground and then have a voltage level placed on the traditional source and another voltage level placed on the control gate, and allowing the cell bit line to charge up. The bit line of the memory cell will then charge up until the bit line voltage becomes sufficiently high to shut off any further cell conduction. The rise of the bit line voltage will occur at a rate and to a level dependent upon the data state of the cell, and the cell will then shut off when the bit line reaches a high enough level such that the body effect affected memory cell threshold is reached, at which point the current essentially shuts off. A particular embodiment performs multiple such sensing sub-operations, each with a different control gate voltage, but with multiple states being sensed in each operation by charging the previously discharged cells up through their source.

    摘要: Various embodiments are directed to different methods and systems relating to design and implementation of memory cells such as, for example, static random access memory (SRAM) cells. In one embodiment, a memory cell may include a first layer of conductive material and a second layer of conductive material. The first layer may include a first gate region and a first interconnect region, and the second layer of conductive material may include a second gate region and a second interconnect region. It will be appreciated that the various techniques described herein for using multiple layers of conductive material to form interconnect regions and/or gate regions of memory cells provides extra degrees of freedom in fine tuning memory cell parameters such as, for example, oxide thickness, threshold voltage, maximum allowed gate voltage, etc.

    摘要: A non-volatile memory device has a channel region between source/drain regions, a floating gate, a control gate, a first dielectric region between the channel region and the floating gate, and a second dielectric region between the floating gate and the control gate. The first dielectric region includes a high-K material. The non-volatile memory device is programmed and/or erased by transferring charge between the floating gate and the control gate via the second dielectric region.

    摘要: An array of a pillar-type nonvolatile memory cells (803) has each memory cell isolated from adjacent memory cells by a trench (810). Each memory cell is formed by a stacking process layers on a substrate: tunnel oxide layer (815), polysilicon floating gate layer (819), ONO or oxide layer (822), polysilicon control gate layer (825). Many aspects of the process are self-aligned. An array of these memory cells will require less segmentation. Furthermore, the memory cell has enhanced programming characteristics because electrons are directed at a normal or nearly normal angle (843) to the floating gate (819).
