ABSTRACT:
Systems and methods are disclosed for modifying soft-programming trims of a non-volatile memory device, such as a flash memory device. The soft-programming trims may be modified based on a count of erase pulses applied to memory cells of the memory device. The number of erase pulses used to erase memory cells may be indicative of accumulated charge in the memory cell. The start voltage, step size, pulse width, number of pulses, pulse ramp, ramp rate, or any other trim of the soft-programming operation may be modified in response to the number of erase pulses.
