  • Patent number: 12254927
    Abstract: Control logic in a memory device causes a programming pulse of a set of programming pulses to be applied to a wordline associated with a memory cell of a memory device, where the memory cell is to be programmed to a target voltage level representing a first programming level. At a first time, first data is caused to be stored in a cache, the first data indicating that a threshold voltage of a memory cell exceeds the target voltage level. At a second time, the cache is caused to be refreshed to store second data indicating that the threshold voltage of the memory cell is less than the target voltage level. In view of the second data, a level shifting operation associated with the memory cell is caused to be executed.

  • Patent number: 12014778
    Abstract: Control logic in a memory device causes a first programming pulse of a set of programming pulses associated with a programming algorithm to be applied to a wordline associated with a memory cell to be programmed to a first target voltage level representing a first programming level. The control logic further performs a program verify operation corresponding to the first programming level to determine that a threshold voltage of the memory cell exceeds the first target voltage level. The control logic further causes first data to be stored in a cache, the first data indicating that the threshold voltage of the memory cell exceeds the first target voltage level. The cache is caused to be refreshed to store second data indicating that the threshold voltage of the memory cell is less than the first target voltage level. In view of the second data, a further programming pulse is caused to be applied to the wordline associated with the memory cell at a reduced programming stress level.

  • Publication number: 20230207018
    Abstract: Control logic in a memory device causes a programming pulse of a set of programming pulses associated with a programming algorithm to be applied to a selected wordline associated with a set of memory cells to be programmed to a target voltage level representing a programming level. Voltage levels of the selected wordline and one or more unselected wordlines of the memory array are discharged to approximately a ground voltage level and a bitline voltage level is applied to a bitline corresponding to the programming level. The selected wordline and a set of unselected wordlines are charged to approximately a pass voltage level followed by the discharge of the selected wordline to a reverse bias level to establish an erase voltage level on the set of memory cells. The control logic further performs a program verify operation corresponding to the programming level associated with the set of memory cells.
