A program method for a flash memory semiconductor device includes the steps of providing a bit line voltage for programming a group of memory cells and detecting if the bit line voltage meets a selected target voltage. When the bit line voltage meets the selected target voltage, a program operation is performed on the group of memory cells. When the bit line voltage does not meet the selected target voltage, the programming operation is individually performed on at least a first subgroup of memory cells from the group and a second subgroup of memory cells from the group.
