    Abstract: A memory array and a structure of the memory array are provided. The memory array includes flash transistors, word lines and bit lines. The flash transistors are arranged in columns and rows. The flash transistors in each column are in serial connection with one another. The word lines are respectively coupled to gate terminals of a row of the flash transistors. The bit lines are respectively coupled to opposite ends of a column of the flash transistors. Band-to-band tunneling current at a selected flash transistor is utilized as read current during a read operation.

  • Publication number: 20240192895
    Abstract: A host system operates to manage a storage device. The host system initiates an abort of a command when the command has been fetched from a submission queue (SQ) of the host system and the SQ entry has been fetched from the SQ and the host system has not received a corresponding command completion response from the storage device. The host system sends an abort request to the storage device, and issues a cleanup request to direct a 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 to indicate completion of the abort request.

  • Publication number: 20240147376
    Abstract: Apparatus and methods are provided for thermal throttling for UE configured with multi-panel transceiving on FR2. In one novel aspect, the UE prioritizes throttling actions based on signal qualities of each transceiving panel. In one embodiment, the switching to the target panel from the active panel is selected as the highest priority throttling action when the signal quality of the target panel is similar to the active panel. In another embodiment, the UE further determines if the quality of the target panel is sufficient to support mmW transceiving before switching to the target panel. In one embodiment, the UE reduces one or more antennae of an active panel when the signal quality difference between the active panel and the target panel is bigger than a predefined gap threshold.

  • Patent number: 11964811
    Abstract: A liquid storage tank includes a housing, a piston located in the housing, a cover, an elastic element, and an outlet pipe. The cover is attached to the housing and has a support post extending toward the piston. The piston, the housing, and the cover define a tank chamber. The tank chamber is filled with cooling liquid. The elastic element is connected with the tank hosing and the piston. The elastic element is free from contact with the cooling liquid. The outlet pipe communicates with the tank chamber. An extension direction of an opening of the outlet pipe is not parallel to a direction of movement of the elastic element. When the cooling liquid is decreased, the piston compressed the tank chamber such that the elastic element is released. The tank chamber is continuously compressed by pairing the elastic element and the piston.
