Abstract
A non-volatile memory unit cell includes a first transistor pair and first and second control gates. The first transistor pair includes first and second transistors that are connected in series and of the same type. The first and second transistors have a first floating polysilicon gate and a second floating polysilicon gate, respectively. The first control gate is coupled to the first floating polysilicon gate through a tunneling junction and the second control gate is coupled to the second floating polysilicon gate through another tunneling junction.
