摘要： An area-efficient gated diode includes a semiconductor layer of a first conductivity type, an active region of a second conductivity type formed in the semiconductor layer proximate an upper surface of the semiconductor layer, and at least one trench electrode extending substantially vertically through the active region and at least partially into the semiconductor layer. A first terminal of the gated diode is electrically connected to the trench electrode, and at least a second terminal is electrically connected to the active region. The gated diode is operative in one of at least a first mode and a second mode as a function of a voltage potential applied between the first and second terminals. The first mode is characterized by the creation of an inversion layer in the semiconductor layer substantially surrounding the trench electrode. The gated diode has a first capacitance in the first mode and a second capacitance in the second mode, the first capacitance being substantially greater than the second capacitance.

摘要： An integrated circuit, such as a memory macro, includes multiple power rails supporting first and second voltage differentials, with the second voltage differential being smaller than the first voltage differential. Signal lines in the integrated circuit are driven with the small voltage swing, which is generated by small swing circuits. The integrated circuit further includes regeneration circuits, which are receiving small voltage swing inputs and are outputting first, or full voltage swings.

摘要： A circuit comprises a control line and a two terminal semiconductor device having first and second terminals. The first terminal is coupled to a signal line, and the second terminal is coupled to the control line. The two terminal semiconductor device is adapted to have a capacitance when a voltage on the first terminal relative to the second terminal is above a threshold voltage and to have a smaller capacitance when a voltage on the first terminal relative to the second terminal is below the threshold voltage. The control line is coupled to a control signal and the signal line is coupled to a signal and is output of the circuit. A signal is placed on the signal line and voltage on the control line is modified (e.g., raised in the case of n-type devices, or lowered for a p-type devices). When the signal falls below the threshold voltage, the two terminal semiconductor device acts as a very small capacitor and the output of the circuit will be a small value. When the signal is above the threshold voltage, the two terminal semiconductor device acts as a large capacitor and the output of the circuit will be influenced by both the value of the signal and the value of the modified voltage on the control line and therefore the signal will be amplified.
