  • Publication number: 20220375762
    Abstract: The embodiments of the present disclosure provide an etching method, an air-gap dielectric layer, and a dynamic random-access memory. The etching method is configured to selectively etch a silicon oxide film on a wafer surface that includes the silicon oxide film and a silicon nitride film. In addition, the etching method includes: a surface layer removal process including: etching the silicon oxide film at a first etching rate and removing a surface modification layer covering on the silicon nitride film; and an etching process including: etching the silicon oxide film at a second etching rate. The first etching rate is smaller than the second etching rate. In the etching method according to the present disclosure, through selectively etching the silicon oxide film, a substantial degradation of an etching selectivity ratio of SiO2/SiN caused by the surface modification layer on the wafer surface can be avoided.

  • Publication number: 20220365724
    Abstract: A host system initiates an abort of a command that has been placed into a submission queue (SQ) of the host system. The host system identifies at least one of a first outcome and a second outcome. When the first outcome indicates that the command is not completed and the second outcome indicates that the SQ entry has been fetched from the SQ, the host system sends an abort request to a storage device, and issues a cleanup request to direct the host controller to reclaim host hardware resources allocated to the command. The host system adds a completion queue (CQ) entry to a CQ and sets an overall command status (OCS) value of the CQ entry based on at least one of the first outcome and the second outcome.

  • Patent number: 11503638
    Abstract: A data unit (e.g., a physical layer convergence procedure (PLCP) protocol data unit (PPDU)) is detected at a first wireless device of a basic service set (BSS). The data unit was sent on a channel from a second wireless device of an overlapping basic service set (OBSS). The data unit is wide-bandwidth, occupying both a primary channel and a secondary channel of the wireless network. The first and second wireless devices are within a same spatial reuse group (SRG). The first wireless device stores the channel bandwidth of the data unit and a receive duration time of the data unit. During the receive duration time of the data unit, a SRG OBSS power density threshold is applied on the secondary channels that are within the channel bandwidth of the data unit, instead of applying a non-SRG OBSS power density threshold on those secondary channels.

    Abstract: A host system coupled to a storage system provides hardware support for command abort. The host system includes a host controller, which detects that a host driver has disabled an enable indicator of a submission queue (SQ). In response to the detection, the host controller stops further fetching from the SQ. The host controller sends all entries that have been fetched from the SQ to the storage device, and sets a status indicator of the SQ to indicate stopped fetching of the SQ.
