PCIe interface device and operating method
SK hynix Inc., Icheon-si, Korea, has been assigned a patent (11809344) developed by Jeon, Yong Tae, Icheon-si, Korea, for “peripheral component interconnect express interface device and operating method thereof.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A Peripheral Component Interconnect Express (PCIe) interface device includes a PCIe layer and a PCIe controller. The PCIe layer performs communication between a host and a Direct Memory Access (DMA) device. The PCIe controller switches an operating clock from a PCIe clock generated based on a reference clock to an internal clock, processes data of the PCIe layer on the basis of the internal clock, and recovers a link with respect to the host, when a reset signal received from the host is asserted or the reference clock is off.”

PCIe device and computing system including same
SK hynix Inc., Icheon-si, Korea, has been assigned a patent (11797468) developed by Jeon, Yong Tae, Icheon-si, Korea, for “peripheral component interconnect express device and computing system including the same.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A PCIe device setting, when a fail lane is detected during a link setting operation, a link by using remaining lanes includes a plurality of lanes comprising a plurality of ports, and a link controller setting a link including the plurality of lanes, wherein the link is set to have a link width that includes remaining lanes, except for a fail lane from among the plurality of lanes, wherein the fail lane from among the plurality of lanes has a state in which the fail lane is unable to form a link with remaining lanes that have not failed from among the plurality of lanes.”

The patent application was filed on 2021-10-21 (17/506889).

PCIe interface system and method of operating
SK hynix Inc., Icheon-si, Korea, has been assigned a patent (11789658) developed by Jeon, Yong Tae, Icheon-si, Korea, for “peripheral component interconnect express (PCIe) interface system and method of operating the same.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A peripheral component interconnect express (PCIe) interface system is provided to include a PCIe interface device, a host, and a non-volatile memory express (NVMe) device connected to the host through the interface device. The host includes a host memory configured to store information on a command to be executed on the NVMe device and a command that has been executed on the NVMe device, and an NVMe driver configured to transmit the command to be executed on the NVMe device to the host memory, and output a doorbell signal indicating that the command to be executed on the NVMe device has been stored in the host memory to the NVMe device. The NVMe device requests to the host memory to register a lightweight notification (LN) indicating a position in which the command to be executed on the NVMe device is stored.”

The patent application was filed on 2021-11-09 (17/522810).

PCIe interface and interface system
SK hynix Inc., Icheon-si, Korea, has been assigned a patent (11782792) developed by Jeon, Yong Tae, Park, Dae Sik, and Jang, Jae Young, Icheon-si, Korea, for “PCIe interface and interface system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A device is provided to include: a transceiver configured to transmit and receive data, and a skip ordered set (SKP OS) control logic in communication with the transceiver and configured to generate an SKP OS and control the transceiver to transmit the SKP OS and a data block to a link connecting to an external device and including a plurality of lanes. The SKP OS control logic is configured to increase or decrease transmission interval of the SKP OS based on a transmission history of the SKP OS, in response to an entry of the link to a recovery state that is used to recover the link from an error.”
