  • Method for applying variable row BIAS to reduce program disturb in a flash memory storage array
    Patent number: 6181599
    Abstract: Program disturb in a Flash storage array is reduced by applying a voltage level that depends on the threshold level of a previously programmed cell to the word-line of that cell during programming of subsequent cells on the same bit-line. By applying higher voltages to word-lines containing unselected programmed memory cells with higher threshold voltages, program disturb due to these higher threshold cells is reduced.
