Patent number: 11474590Abstract: Bandwidth for information transfers between devices is dynamically changed to accommodate transitions between power modes employed in a system. The bandwidth is changed by selectively enabling and disabling individual control links and data links that carry the information. During a highest bandwidth mode for the system, all of the data and control links are enabled to provide maximum information throughout. During one or more lower bandwidth modes for the system, at least one data link and/or at least one control link is disabled to reduce the power consumption of the devices. At least one data link and at least one control link remain enabled during each low bandwidth mode. For these links, the same signaling rate is used for both bandwidth modes to reduce latency that would otherwise be caused by changing signaling rates. Also, calibration information is generated for disabled links so that these links may be quickly brought back into service.Type: GrantFiled: July 6, 2020Date of Patent: October 18, 2022Assignee: Rambus Inc.Inventor: Frederick A.

Patent number: 11429172Abstract: A power supply architecture combines the benefits of a traditional single stage power delivery, when there are no additional power losses in the integrated VR with low VID and low CPU losses of FIVR (fully integrated voltage regulator) and D-LVR (digital linear voltage regulator). The D-LVR is not in series with the main power flow, but in parallel. By placing the digital-LVR in parallel to a primary VR (e.g., motherboard VR), the CPU VID is lowered and the processor core power consumption is lowered. The power supply architecture reduces the guard band for input power supply level, thereby reducing the overall power consumption because the motherboard VR specifications can be relaxed, saving cost and power. The power supply architecture drastically increases the CPU performance at a small extra cost for the silicon and low complexity of tuning.Type: GrantFiled: January 6, 2020Date of Patent: August 30, 2022Assignee: Intel CorporationInventors: Alexander Uan-Zo-Li, Eugene Gorbatov, Harish Krishnamurthy, Alexander Lyakhov, Patrick Leung, Stephen Gunther, Arik Gihon, Khondker Ahmed, Philip Lehwalder, Sameer Shekhar, Vishram Pandit, Nimrod Angel, Michael Zelikson
