  • Patent number: 11967387
    Abstract: Processing logic in a memory device initiates a program operation on a memory array, the program operation comprising a program phase and a program verify phase. The processing logic further causes a negative voltage signal to be applied to a first selected word line of a block of the memory array during the program verify phase of the program operation, wherein the first selected word line is coupled to a corresponding first memory cell of a first plurality of memory cells in a string of memory cells in the block, wherein the first selected word line is associated with the program operation.
    Type: Grant

  • Publication number: 20240120010
    Abstract: Control logic in a memory device initiates a program operation on a memory array, the program operation comprising a seeding phase. During the seeding phase, the control logic causes a seeding voltage to be applied to a string of memory cells in a data block of the memory array during the seeding phase of the program operation and causes a first positive voltage to be applied to a first plurality of word lines of the data block during the seeding phase, wherein each of the first plurality of word lines is coupled to a corresponding memory cell of a first plurality of memory cells in the string of memory cells, the first plurality of word lines comprising a selected word line associated with the program operation.

  • Publication number: 20230197164
    Abstract: Control logic can perform operations including obtaining, for each dummy wordline of a set of dummy wordlines, a respective set of step-up voltage parameters, wherein each set of step-up voltage parameters includes a step ratio corresponding to the dummy wordline, and causing a bias voltage with respect to each dummy wordline of the set of dummy wordlines to be ramped to a respective program inhibit bias voltage in accordance with the respective set of step-up voltage parameters. Additionally or alternatively, control logic can perform memory operations including causing a bias voltage with respect to each dummy wordline to be ramped to a power supply voltage during a seed first sub-phase of a pre-programming phase, and maintaining the bias voltage of the first dummy wordline at a first dummy wordline seed voltage throughout a bitline setting sub-phase of the pre-programming phase.
