  • Publication number: 20220188499
    Abstract: Area and routing overhead issues of traditional anamux incorporation in a semiconductor device are overcome by placing a functional anamux block on top of an I/O pad. In some embodiments, multiple anamux blocks can be stacked either vertically or placed on neighboring I/O pads for horizontal stacking. Embodiments provide the anamux blocks as the same width as the I/O pads and the width is optimized to minimize padring height. In some embodiments, a power/ground I/O (PGE) bond pad architecture is enabled by the incorporation of both I/O pad and anamux blocks in the same region, providing two bonding regions, which can further reduce chip area. Some embodiments also permit routing of signals through the anamux block to neighoring blocks and the I/O channels.

  • Patent number: 11354408
    Abstract: A memory controller for a (DRAM) memory processes an (access) command for a target row in the memory, increments a count value for each victim row associated with the target row, and issues a (dummy activate) command for a victim row whose count value reaches a specified threshold. By tracking victim rows instead of target rows, the memory controller can thwart both single-sided and double-sided row-hammer attacks. The memory controller maintains the victim-row addresses and corresponding command counts in a TCAM memory to detect rows that may be prone to row-hammer attacks. If so, then the memory controller issues dummy activate commands to the corresponding memory rows to thwart such row-hammer attacks.

  • Patent number: 11353549
    Abstract: A data processing device and method for detecting interference in a FMCW radar system are described. For each of a plurality of transmitted chirps of the radar system, a high pass filter is applied to a receiver signal of a receiver channel of a radar receiver during an acquisition time corresponding to a transmitted chirp to remove those parts of the receiver signal corresponding to a reflected chirp having a power at the radar receiver greater than the noise power of the radar receiver of the radar system. The receiver signal power is calculated from the high pass filtered receiver signal. The receiver signal power is compared with a threshold noise power based on an estimate of the thermal noise of the radar receiver to determine whether the receiver signal corresponds to an interfered received chirp including interference or a non-interfered received chirp not including interference.
