Patent number: 10990151Abstract: In embodiments, an apparatus includes a burst current monitor, to detect a burst of input current drawn by a SSD from a host above a pre-defined burst threshold, and control logic coupled to the burst current monitor. The control logic, in response to the detection by the burst current monitor of the input current above the burst threshold, causes a capacitor of the SSD to supply an assistance current to the SSD, to reduce the input current drawn by the SSD. In embodiments, the capacitor is a hold-up capacitor disposed in a PLI circuit of the SSD, and the apparatus is integrated within a hold-up control logic sub-circuit of the PLI circuit.Type: GrantFiled: March 5, 2019Date of Patent: April 27, 2021Assignee: Intel CorporationInventors: Knut Grimsrud, Adrian Mocanu, Andrew Morning-Smith, Zeljko Zupanc

Patent number: 10936049Abstract: An apparatus is described. The apparatus includes a power management integrated circuit (PMIC) semiconductor chip having logic circuitry to implement a PMIC/PMIC interface having a downstream signal line and an upstream signal line. The downstream signal line to communicate any of multiple states that a downstream PMIC semiconductor chip is to implement with one of multiple voltage levels, where, different ones of the multiple voltage levels correspond to different ones of the multiple states. The upstream signal line is to communicate whether or not the downstream PMIC semiconductor chip is ready to receive a next one of the multiple voltage levels.Type: GrantFiled: April 26, 2019Date of Patent: March 2, 2021Assignee: Intel CorporationInventors: Adrian Mocanu, Andrew Morning-Smith, Zeljko Zupanc, Derrick Wilson
