Abstract
A programming switch for non-volatile memory integrated circuit mainly comprises of: (1) one programming voltage Vpp generated inside circuit by itself, and with typical value between 15 volt to 20 volt; (2) one supplied power Vcc which is external power; (3) one input end whose voltage Vin with two different values, logical "1" and logical "0"; (4) one output end with voltage Vout; (5) two mutually inverse clock signal CK and CKB, which functions only when input voltage is logical "1"; (6) one first node and one second node; (7) one first enhanced NMOS transistor whose gate is connected to the second node, drain and source connecting between the programming voltage Vpp and the first node; (8) one second enhanced NMOS transistor for connecting to diode, whose gate is connected to the first node, drain and source connecting between the first node and the second node; (9) one third enhanced NMOS transistor for connecting to diode, whose gate is connected to the second node, drain and source connecting between the second node and the output end; (10) one fourth enhanced NMOS transistor for connecting to diode, whose gate is connected to the supplied power Vcc, drain and source connecting between the input end and the output end; (11) one capacitor couples, in which one end of first capacitor is connected to the clock signal CK, the other end connected to the first node, one end of second capacitor is connected to the clock signal CKB, the other end connected to the second node; (12) making the relationship between the output end voltage Vout and the input end voltage Vin become that when Vin is logical "0", Vout is also logical "0", when Vin is logical "1", Vout is about Vpp or logical "1".
