    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.

    Abstract: Control logic in a memory device causes a program voltage to be applied to a selected data wordline of a plurality of wordlines of a block of a memory array for a pulse duration period during a programming operation. The control logic further causes a first pass voltage to be applied to one or more unselected data wordlines of the plurality of wordlines of the block for the pulse duration period and causes a second pass voltage to be applied to a last unselected data wordline of the plurality of wordlines of the block for at least a first portion of the pulse duration period, wherein the second pass voltage has a lower magnitude than the first pass voltage.

    Abstract: Various embodiments provide for performing a memory operation, such as a memory block compaction operation or block folding or refresh operation, based on a temperature associated with a memory block of a memory device. For instance, some embodiments provide for techniques that can cause performance of a block compaction operation on a memory block at a temperature that is at least at or higher than a predetermined temperature value. Additionally, some embodiments provide for techniques that can cause performance of a block folding/refresh operation, at a temperature that is at or higher than the predetermined temperature value, on one or more blocks on which data was written at a temperature lower than the predetermined temperature value.
