  • Patent number: 12073903
    Abstract: A method may be performed by a leakage monitoring and compensation system configured to estimate and compensate for leakage current in memory unit cells. The method may include identifying a leakage monitoring component associated with a memory unit cell. Further, the method may include sampling multiple leak events during a first exposure window. The method may include storing a first count representing the plurality of leak events sampled during the first exposure window. Each leak event may correspond to a unit of memory leakage. The method may include sampling multiple sensing events during a second exposure window. The method may include detecting a second count representing the sensing events sampled during the second exposure window. The method may include determining a compensation value representing a difference between the first count and the second count.

  • Patent number: 11750009
    Abstract: An apparatus may include a power rail, a subassembly, an additional subassembly, and an interface coupling the subassembly to the additional subassembly. The subassembly may include a load, an energy-storing component, a charger having an output coupled to the energy-storing component, and a reverse-current limiter having a first terminal coupled to the energy-storing component. The additional subassembly may include an additional energy-storing component, an additional charger having an output coupled to the additional energy-storing component, and an additional reverse-current limiter having a first terminal coupled to the additional energy-storing component. The power rail may cross the interface and may couple the load, an input of the charger, a second terminal of the reverse-current limiter, an input of the additional charger, and a second terminal of the additional reverse-current limiter. Various other apparatuses, systems, and methods are also disclosed.
