Dynamic sense node voltage to compensate for variances when sensing threshold voltages of memory cells
11626160 · 2023-04-11 · ·

Technology for sensing non-volatile memory cells in which one or more sense nodes are charged to a sense voltage having a magnitude that improves sensing accuracy. One sense node may be charged to different sense voltages when sensing different memory cells at different times. Multiple sense nodes may be charged to a corresponding multiple different sense voltages when sensing different memory cells at the same time. The one or more sense nodes are allowed to discharge based on respective currents of memory cells for a pre-determined time while applying a reference voltage to the memory cells. The Vts of the selected memory cells are assessed based on respective voltages on the one or more of sense nodes after the pre-determined time. Different sensing voltages may be used based on bit line voltage, bit line resistance, distance of memory cells from the sense node, or other factors.

Non-volatile memory with sub-block based self-boosting scheme

To help reduce program disturbs in non-selected NAND strings of a non-volatile memory, a sub-block based boosting scheme in introduced. For a three dimensional NAND memory structure, in which the memory cells above a joint region form an upper sub-block and memory cells below the joint region form a lower sub-block, dummy word lines in the joint region act as select gates to allow boosting at the sub-block level when the lower block is being programmed in a reverse order.
