An apparatus is provided which comprises: a plurality of devices coupled to an input power supply rail and an output power supply rail; a first circuitry coupled to the plurality of devices, wherein the first circuitry is to turn on or off one or more devices of the plurality according to a control; and a second circuitry coupled to the first circuitry, wherein the second circuitry comprises an all-digital proportional-derivative mechanism to generate the control according to a digital representation of voltage on the output power supply rail.

Apparatus for improving read stability

Methods and systems to implement voltage level shifting with interim-voltage-controlled contention-interruption. A voltage level shifter (VLS) may include voltage level shift circuitry to level shift an input logical state from an input voltage swing to an output voltage swing. The VLS may include contention circuitry, a contention interrupter, and an interrupt controller to generate a contention-interrupt control having an interim voltage swing. A lower limit of the interim voltage swing may correspond to a lower limit of the output voltage swing. An upper limit of the interim voltage swing may correspond to an upper limit of the input voltage swing. The VLS may be implemented to level shift true and complimentary logical states, such as with cascode voltage switch logic (CVSL). The interim-voltage-controlled contention interrupter may help to maintain voltages within process-based voltage reliability limits of the contention interrupter, with relatively little delay, and relatively little power and area consumption.

Voltage level shift with interim-voltage-controlled contention interrupt

Methods and systems to dynamically control state-retention strengths of a plurality of memory cells during a write operation to a subset of the memory cells. Dynamic control may include weakening state-retention strengths of the plurality of memory cells during a write operation to a subset of the memory cells, while preserving state-retention abilities of remaining ones of the plurality of memory cells. Weakening may include adjusting one or more resistances between one or more power supplies and the plurality of memory cells. Dynamic control may be selectively performed on portions of each of the memory cells in response to an input data logic state. Dynamic control may reduce a write contention within the subset of memory cells without disabling state-retention abilities of remaining ones of the plurality of memory cells, and may improve write response times of the memory cells.
