CMOS switching devices are connected to testing equipment that applies AC to stress the CMOS switching devices. The testing equipment varies rise and fall times of drain and gate voltages, and varies offsets of the drain and gate voltages of the CMOS switching devices. The amount of hot carrier injection (HCI) within the CMOS switching devices is measured when the rise and fall times of the drain and gate voltages cross over, to establish AC HCI contribution to device degradation of the CMOS switching devices. Further, these methods can correlate the AC HCI contribution of the CMOS switching devices to CMOS logic devices based on ring oscillator (RO) degradation of ROs similarly tested or simulated, to produce AC HCI contribution for the CMOS logic devices.

An integrated circuit with a transistor advantageously embodied in a laterally diffused metal oxide semiconductor device having a gate located over a channel region recessed into a semiconductor substrate and a method of forming the same. In one embodiment, the transistor includes a source/drain including a lightly or heavily doped region adjacent the channel region, and an oppositely doped well extending under the channel region and a portion of the lightly or heavily doped region of the source/drain. The transistor also includes a channel extension, within the oppositely doped well, under the channel region and extending under a portion of the lightly or heavily doped region of the source/drain.

Methods are provided for operating a memory device. An exemplary method involves obtaining a standby current through a memory block and adjusting a supply voltage for the memory block based on the obtained standby current. An exemplary memory device includes a block of one or more memory cells, a voltage regulating element coupled to the block to provide a supply voltage to the block, a current sensing element coupled to the block to measure current through the block, and a control module coupled to the voltage regulating element and the current sensing element to adjust the supply voltage provided by the voltage regulating element based on a measured current through the block obtained from the current sensing element.
