  • Publication number: 20210104280
    Abstract: Method for performing an erase program operation. Various methods include: erasing a block of cells by: applying a program pulse to a block of memory elements in the three-dimensional memory that programs the block of memory elements to a level below an erase verify level, where the three-dimensional memory comprises memory elements stacked vertically; performing a verify step to verify voltage levels of a group of memory elements; determining that a memory element of the group is outside of a threshold window defined between the erase verify level and a compact erase threshold amount; and applying a second program pulse to the memory element. Where erasing the block of memory elements creates an erased block, where a width of the voltage distribution of the erased memory elements in the erased block is the same as or below a width of a voltage distribution associated with programmed memory elements.
