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.
