Original Abstract Submitted

A memory device includes a memory array and control logic, operatively coupled to the memory array, to perform operations including identifying an erased block of the memory array, causing a set of cells addressable by a target wordline of the erased block to be set to a target threshold voltage, determining an amount of threshold voltage shift with respect to the target threshold voltage after a delay, determining whether the amount of threshold voltage shift satisfies a threshold condition defined by a target data retention metric, and in response to determining that the amount of threshold voltage shift is sufficient, releasing the erased block for programming.
