Abstract

The storage device comprises a non-volatile memory coupled to a controller. The controller is configured to determine a first programming voltage by performing at least one program-verify iteration on a first word line using a voltage value which starts as a predetermined first initial voltage and is sequentially increased by a first voltage step amount following each failure to successfully program until the programming is completed. The controller is also configured to determine a second initial programming voltage by decreasing the first programming voltage by a second voltage step amount. The controller is further configured to perform at least one program-verify iteration on a second word line of the plurality of word lines using a voltage value which starts as the second initial programming voltage and is increased by the first voltage step amount following each sequential failure to successfully program until the programming is completed.
