Patent number: 11176991Abstract: Low-power compute-in-memory (CIM) systems employing CIM circuits that include static random access memory (SRAM) bit cells circuits. The CIM circuits can be used for multiply-and-accumulate (MAC) operations. The CIM circuits can include five-transistor (5T) SRAM bit cells that each have a single bit line coupled to an access circuit for accessing the SRAM bit cell for read/write operations. The CIM circuit also includes a multiplication circuit (e.g., an exclusive OR (XOR)-based circuit) coupled to the SRAM bit cell. The CIM circuit is configured to perform multiplication of an input data value received by the multiplication circuit with a weight data value stored in the SRAM bit cell. The reduction of an access circuit in the 5T SRAM bit cell allows the pull-up voltage at a supply voltage rail coupled to the inverters of the 5T SRAM bit cell to be reduced to reduce standby power while providing storage stability.Type: GrantFiled: October 30, 2020Date of Patent: November 16, 2021Assignee: QUALCOMM IncorporatedInventors: Khaja Ahmad Shaik, Bharani Chava, Dawuth Shadulkhan Pathan

Patent number: 11177862Abstract: A hybrid class B channel state information (CSI) reference signal (CSI-RS) scheme is discussed which configures one cell-common beamformed CSI-RS resource for beam tracking and another UE-specific beamformed CSI-RS resource for CSI feedback. The cell-common beamformed CSI-RS resource may be transmitted at a longer periodicity and shared by user equipments (UEs) in the cell. The beamforming may be cycled over a set of predefined weights transparent to UE. The UE-specific beamformed CSI-RS may be transmitted at a shorter periodicity and can be activated dynamically to allow resource sharing among multiple UEs. The UEs will report a CSI for the cell-common beamformed CSI-RS resource which provides a quality indicator for the associated cell-common beam and is utilized by the base station to determine the precoding weight for the UE-specific beamformed CSI-RS resource. Both resources can be configured with different parameter sets, such as number of ports, codebook type, and CSI reporting parameters.Type: GrantFiled: May 10, 2017Date of Patent: November 16, 2021Assignee: QUALCOMM IncorporatedInventors: Chao Wei, Yu Zhang, Bo Chen, Jilei Hou
