Patent number: 10999533Abstract: Extension devices such as upstream facing port devices (UFP devices) and downstream facing port devices (DFP devices) connect via an extension medium. When a UFP device and a DFP device pair with each other, DisplayPort video and/or audio information from a DisplayPort source device can be presented by a DisplayPort sink device, which are coupled to the UFP device and DFP device, respectively. In some embodiments, the DFP device may train a DisplayPort link to the DisplayPort sink device regardless of whether it is receiving actual data from a UFP device, and may provide placeholder data to the DisplayPort sink device in order to keep the link active. The DFP device may then replace the placeholder data with the actual data from the UFP device, once received, and may thereby seamlessly switch the DisplayPort sink device from presenting placeholder data to presenting data from the DisplayPort source device.Type: GrantFiled: May 26, 2020Date of Patent: May 4, 2021Assignee: Icron Technologies CorporationInventors: Bhupinder Singh Rathore, Ardeshir Saghafi, Sukhdeep Singh Hundal

Patent number: 10520998Abstract: Embodiments of the present disclosure provide systems and/or methods for managing power distribution over a USB topology. In some embodiments, a host device is coupled to an upstream facing port device (UFP device) via a USB compliant connection, and a USB device is coupled to a downstream facing port device (DFP device) via a USB compliant connection. The UFP device and DFP device are connected via a non-USB compliant extension medium. In various embodiments, the UFP device and DFP device may be individually powered by different types of sources (such as external power sources, power distributed over the extension medium, batteries, USB bus power, and/or the like). The UFP device and DFP device cooperate to provide USB power distribution functionality throughout the USB topology despite the presence of the non-USB compliant extension medium.Type: GrantFiled: July 3, 2017Date of Patent: December 31, 2019Assignee: Icron Technologies CorporationInventors: Sukhdeep Singh Hundal, Thomas Aaron Schultz, Ardeshir Saghafi

Patent number: 10331611Abstract: In some embodiments, the present disclosure provides techniques for reducing an amount of bandwidth used for the communication of DisplayPort information via a USB Type-C receptacle. In some embodiments, this reduction in bandwidth allows for the concurrent exchange of USB 2.0 information, SuperSpeed information, and four lanes of DisplayPort information via a single USB Type-C receptacle. In some embodiments, this may be accomplished in part by processing the information from the four DisplayPort lanes to be transmittable via two differential pairs of the USB Type-C connection, thereby providing four lanes of DisplayPort communication over the USB Type-C connection concurrently with SuperSpeed information. In some embodiments, the reduction in bandwidth of the DisplayPort information may be used for other purposes, such as transmitting high bandwidth DisplayPort information over a cable or connector of a low quality that would otherwise not support such an exchange.Type: GrantFiled: December 28, 2018Date of Patent: June 25, 2019Assignee: Icron Technologies CorporationInventors: Sukhdeep Singh Hundal, Ardeshir Saghafi

The forward write procedure begins at a top location of the memory device. The compression module concurrently performs a reverse write procedure to store second components and third components of the compressed information sequentially in an interlaced configuration. The reverse write procedure begins at a bottom location of the memory device.Type: GrantFiled: April 1, 2005Date of Patent: June 3, 2008Assignee: Seiko Epson CorporationInventors: Jimmy Kwok Lap Lai, Ardeshir Saghafi
