Abstract:
1. A two terminal programmable non-volatile device situated on a substrate, the device comprising: a first diffusion region coupled to a first terminal; and a second diffusion region coupled to a second terminal; and a channel coupling said first diffusion region and second diffusion region; a floating gate comprised of polysilicon, which floating gate is situated over at least a portion of said channel; wherein the device is adapted such that a channel hot electron current can be induced in said channel by a voltage potential imposed across said first terminal and said second terminal by a single program voltage, and which voltage potential is sufficient to cause injection into said floating gate and program the device, wherein the first diffusion region overlaps a sufficient areal portion of said floating gate to permit a threshold voltage of the device to be controlled by a coupling ratio determined by said areal portion and said single program voltage applied to said second diffusion region.
