摘要
An only-one-polysilicon layer non-volatile memory unit cell includes a first P-type transistor, a second P-type transistor, a N-type transistor pair, a first and second coupling capacitors is provided. The N-type transistor pair has a third transistor and a fourth transistor that are connected. The third transistor and the fourth transistor have a first floating polysilicon gate and a second floating polysilicon gate to serve as charge storage mediums, respectively. One end of the second coupling capacitor is connected to the gate of the second transistor and is coupled to the second floating polysilicon gate, the other end of the second coupling capacitor receives a second control voltage. One end of the second coupling capacitor is connected to the gate of the second transistor and is coupled to the second floating polysilicon gate, the other end of the second coupling capacitor receives a second control voltage.
