Abstract: Single gate and dual gate FinFET devices suitable for use in an SRAM memory array have respective fins, source regions, and drain regions that are formed from portions of a single, contiguous layer on the semiconductor substrate, so that STI is unnecessary. Pairs of FinFETs can be configured as dependent-gate devices wherein adjacent channels are controlled by a common gate, or as independent-gate devices wherein one channel is controlled by two gates. Metal interconnects coupling a plurality of the FinFET devices are made of a same material as the gate electrodes. Such structural and material commonalities help to reduce costs of manufacturing high-density memory arrays.

Abstract: A half-bridge driver circuit periodically repeats switching cycles by closing a first FET via a first drive signal, detecting an instant when a current flowing through the first FET reaches a threshold and then opening the first FET and closing a second FET via a second drive signal. An error amplifier generates a control voltage by comparing a feedback signal with a reference signal, and a variable current generator generates a first current as a function of the control voltage. The error amplifier includes a proportional-integral controller, and a slope compensation circuit that generates a second current as a ramp signal. The threshold is generated by subtracting the second current from the first current. In response to detecting the instant, the second current is sampled and a signal indicative of the threshold is generated by subtracting the sampled second current from the first current.

Abstract: A circuit includes an electronic switch configured to be coupled intermediate a high-voltage node and low-voltage circuitry and configured to couple the low-voltage circuitry to the high-voltage node. A voltage-sensing node is configured to be coupled to the high-voltage node via a pull-up resistor. A further electronic switch can be switched to a conductive state to couple the voltage-sensing node and the control node of the electronic switch. A comparator compares a threshold with a voltage at the voltage-sensing node and causes the further electronic switch to switch on in response to the voltage at said voltage-sensing node reaching said threshold. A charge pump coupled to the current flow-path of the electronic switch is activated to the conductive state to pump electric charge from the current flow-path of the electronic switch to the control node of the electronic switch via the further electronic switch switched to the conductive state.
