Abstract
A data storage device includes a controller coupled to one or more memory devices. The controller is configured to determine one or more first wordlines within the memory device that needs more than one pulse for programming and one or more second wordlines within the memory device that needs one pulse and no program verify. The locations of the one or more first wordlines and the one or more second wordlines are stored in a data structure of the memory device. During program operations, the controller utilizes the data structure to determine whether the one or more wordlines being programmed requires only one pulse and no program verify or a multi-loop program. The data structure is updated after an EPWR and/or XOR parity operation.
