Abstract
The present invention discloses systems and methods for providing voltages during programming to the control gates of write protect CAMS. Upon entering a write protect CAM programming mode, at least one voltage supply circuit is activated to supply the predetermined voltage for the control gates of the write protect CAMS. When the write protect CAMS are programmed, a gate control circuit transfers a programming voltage to the control gates of the write protect CAMS. Following programming and verification of the write protect CAMS, the gate control circuit holds the control gates of the write protect CAMS at a ground voltage level.
