Abstract
Techniques are provided for predictively programming of non-volatile memory, which may reduce the number of verify operations. In one aspect, a programming circuit is configured to program memory cells to a verify low voltage and to program a set of the memory cells to target states. The set comprises memory cells having a threshold voltage between the verify low voltage and a verify high voltage. To program the set of the memory cells to the target states, the programming circuit is configured to apply two or more program pulses to memory cells in the set without verifying whether the memory cells have reached their respective target states, including: apply a first and second program enable voltages to the bit lines associated with the memory cells having different strengths.
