  • Patent number: 11841732
    Abstract: A predictive clock controller is provided for modifying the frequency of a clock signal provided to a processing unit based on knowledge of the power usage by the application running on the processing unit during different execution periods. The predictive clock controller counts barrier syncs for the application, so as to determine where the application is in its sync schedule. The predictive clock controller is able to determine from the number of counted syncs, when the application will transition from one execution period to another execution period with different power requirements, and to adjust the clock frequency accordingly.

  • Patent number: 11800814
    Abstract: A memory cell having a Josephson junction and a magnetic junction situated in a close proximity to the Josephson junction. The two junctions may be vertically integrated. The magnetic junction has at least two magnetic layers with different coercive forces and a non-magnetic layer therebetween, to form a spin valve or pseudo-spin valve. A magnetization direction of a magnetic layer with lower coercive force can be rotated with respect to the larger coercive force magnetic layer(s). Magnetic fields produced by appropriately configured control lines carrying electric current, or spin-polarized current through the magnetic junction, can result in rotation. The magnetic junction influences the Josephson critical current of the Josephson junction, leading to distinct values of critical current which can serve as digital logic states. The so obtained memory cell can be integrated into the large arrays containing a plurality of the cells, to enable the selective READ and WRITE operations.

  • Patent number: 11769557
    Abstract: Techniques for preventing read disturb in NAND memory devices are described. In one example, reads are tracked for sub-groups. When the number of reads to a sub-group meets a threshold, the data at the wordline on which the threshold was met is moved along with the data at neighboring wordlines to an SLC block without moving the entire block. The performance impact and write amplification impact of read disturb mitigation can be significantly reduced while maintaining some data continuity.
