An NMOS transistor in a high-voltage circuit portion is inserted between the output of a NAND gate and a node, and receives an input signal at the gate electrode thereof. A load current generating portion in the high-voltage circuit portion includes PMOS transistors coupled in series between a high power supply voltage and the node. One of the PMOS transistor receives a control signal at the gate electrode thereof. The other PMOS transistor receives a control signal at the gate electrode thereof. An inverter receives a signal obtained from the node as an input signal, and outputs the inverted signal thereof as an output signal.Type: GrantFiled: January 29, 2009Date of Patent: September 14, 2010Assignee: Renesas Electronics CorporationInventors: Mitsuhiro Tomoeda, Makoto Muneyasu, Masahiro Hosoda

Publication number: 20100165708Abstract: A memory controller and a decoder are provided. The decoder is adapted to the memory controller. The decoder includes a first transistor to a fourth transistor. Gates of the first to the fourth transistor are coupled to a first to a fourth control signal respectively. A first terminal and a second terminal of the first transistor are coupled to a first voltage and a first terminal of the second transistor respectively. First terminals and second terminals of the third transistor and the fourth transistor are coupled to a second terminal of the second transistor and a second voltage respectively. When the first transistor and the second transistor are turned off, a voltage of the second control signal is lower than a voltage of the first control signal. Thereby, a gate-induced drain leakage (GIDL) current of the transistors is reduced.Type: ApplicationFiled: March 4, 2009Publication date: July 1, 2010Applicant: WINBOND ELECTRONICS CORP.Inventor: Cheng-Sheng Lee

Publication number: 20090219778Abstract: A novel methodology for the construction and operation of logical circuits and gates that makes use of and contact to a fourth (4th) terminal (substrates/bodies) of MOSFET devices is implemented by the present invention to realize a novel decode personalization. The novel construction and operation of the decode personalization provides for maintaining body-contacted MOSFET devices at a lower threshold voltage (VTh) when actively on (to increase overdrive and performance), and at a higher relative threshold voltage when off (to reduce leakage power). Because the threshold potential of a transistor moves inversely to its body potential, the body of each device is tied to the inverse of the device's drain voltage to achieve such a desirable threshold potential modulation effect for improved device, circuit, gate, decode personalization and logical family operation.Type: ApplicationFiled: February 28, 2008Publication date: September 3, 2009Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Kerry Bernstein, Wilfried Haensch

Publication number: 20080246514Abstract: A decoder circuit that selects a grayscale voltage responsive to digital input includes a first transistor circuit that selects grayscale voltages greater than a certain voltage and a second transistor circuit that selects grayscale voltages less than the certain voltage. The two transistor circuits are formed in separate substrates, one substrate being a well formed in the other substrate, or both substrates being wells formed in a third substrate. The substrate of the first transistor circuit is biased at a higher potential than the substrate of the second transistor circuit. This biasing scheme enables all selected grayscale voltages to propagate quickly through the decoder circuit.Type: ApplicationFiled: June 13, 2008Publication date: October 9, 2008Applicant: OKI ELECTRIC INDUSTRY CO., LTD.Inventor: Yasutaka Takabayashi
