  • Patent number: 12718891
    Abstract: A non-volatile storage apparatus continuously maintains unselected word lines for multiple regions in multiple blocks at one or more overdrive voltages and continuously maintains unselected select lines for multiple regions in multiple blocks at one or more unselected voltages while performing a read process for non-volatile memory cells in one or more regions of one or more blocks of the same die, without lowering those signals to ground or another resting voltage. Selected word lines are separately temporarily toggled to a read reference voltage to enable reading and then reverted back to an overdrive voltage upon completion of the reading. Selected select lines are separately temporarily toggled to a select voltage to enable reading and then reverted back to an unselected voltage upon completion of the reading.

  • Patent number: 12712032
    Abstract: The memory device includes a memory block with an array of memory cells that are arranged in a plurality of word lines. The memory cells are programmed to one bit per memory cell with each memory cell being either in an erased data state or a programmed data state.

  • Publication number: 20260229301
    Abstract: Technology for NAND memory cells having a large sub-threshold swing for in-memory compute. A NAND memory structure has alternating conductive layers and insulating layers. NAND strings extend perpendicularly through the alternating conducting layers and insulating layers. The NAND strings may be formed in memory holes that contain an insulating core, a channel, a tunnelling layer, a charge trap layer, and a blocking layer. The diameter of the insulating core and the combined thickness of the tunnelling layer, charge trap layer, and blocking layer may be sized to achieve a large sub-threshold swing in the NAND memory cells. To further improve the number of current based data states that can be stored, a ground core structure within the insulating core can introduced along with memory cells with an increased channel length, such as by increasing the relative thickness of the word line layers or shorting together multiple word lines.
