Abstract
A method of programming a dual cell memory device having a first charge storing cell and second charge storing cell. The first charge storing cell can be pre-read to determine if the first charge storing cell stores an amount of charge to increase a threshold voltage of the memory device over a specified threshold voltage. If not, the second charge storing cell can be programmed with a standard program pulse. If so, the second charge storing cell can be programed with a modified program pulse.
