Suppression of Program Disturb with Bit Line and Select Gate Voltage Regulation

Techniques for suppression of program disturb in flash memory devices are described herein. In an example embodiment, a method for suppression of program disturb in a flash memory array is provided. The flash memory array comprises rows and columns of memory cells, where the memory cells in each row are coupled to a source line and to a select-gate (SG) line, and the memory cells in each column are coupled to a respective bit line (BL). During a program memory operation, a first voltage, of a selected SG line, and a second voltage, of an unselected BL, are regulated independently of a power supply voltage of the flash memory array, where the first voltage is regulated in a first range of 0.9V to 1.1V and the second voltage is regulated in a second range of 0.4V to 1.2V.
