Patent number: 11489526Abstract: Described is a level-shifter that can save area between voltage domains with limited voltage differential, and further save power by steering current between two power supply rails. The level-shifter comprises: an input to receive a first signal between a first reference rail and a second reference rail; an output to provide a second signal the first reference rail and a third reference rail, wherein in a voltage level of the third reference rail is higher than a voltage level of the second reference rail, and wherein a voltage level of the first reference is lower than the voltage level of the second reference rail and the third reference rail; and a circuitry coupled to the input and the output, wherein the circuitry is to steer current from the third reference rail to the second reference rail.Type: GrantFiled: May 22, 2020Date of Patent: November 1, 2022Assignee: Intel CorporationInventors: Andres Malavasi Mora, Jaydeep Kulkarni, Anupama Thaploo, Muhammad Khellah

Patent number: 9685208Abstract: Embodiments include apparatuses, methods, and systems related to an assist circuit that may be coupled to one or more components of a memory system to selectively lower a supply voltage that is delivered to the component. For example, the assist circuit may be coupled to a plurality of bitcells (e.g., register file bitcells). The assist circuit may selectively lower the supply voltage delivered to the bitcells during at least a portion of a write operation and/or during an inactive state of the bitcells. Additionally, or alternatively, the assist circuit may be coupled to a read circuit to selectively lower the supply voltage delivered to the read circuit during an inactive state of the read circuit. The assist circuit may include a control transistor coupled in parallel with one or more diodes between a main supply rail and a supply node of the bitcells and/or read circuit.Type: GrantFiled: April 8, 2016Date of Patent: June 20, 2017Assignee: Intel CorporationInventors: Jaydeep P. Kulkarni, Anupama Thaploo, Iqbal Rajwani, Kyung-Hoae Koo, Eric A. Karl, Muhammad Khellah
