Zusammenfassung:A non-volatile memory that includes a shared source line configuration and methods of operating the same to reduce disturbs is provided. In one embodiment, the method includes coupling a first positive high voltage to a first global wordline in a first row of an array of memory cells, and coupling a second negative high voltage (VNEG) to a first bitline in a first column of the array to apply a bias to a non-volatile memory transistor in a selected memory cell to program the selected memory cell. A margin voltage having a magnitude less than VNEG is coupled to a second global wordline in a second row of the array, and an inhibit voltage coupled to a second bitline in a second column of the array.
