Abstract
Programming in a non-volatile memory device includes applying at least one programming pulse to a non-volatile memory cell during a first programming loop; applying at least one programming pulse to the non-volatile memory cell during a second programming loop succeeding the first programming loop; and providing a bitline bias voltage of the non-volatile memory cell according to a result of comparing a threshold voltage of the non-volatile memory cell in the first programming loop with a low verify level and/or a high verify level of a target data state of the non-volatile memory cell and a result of comparing a threshold voltage of the non-volatile memory cell in the second programming loop with the low verify level and/or the high verify level of the target data state of the non-volatile memory cell.
