  • Patent number: 11404138
    Abstract: An apparatus and method for detecting leakage current in a non-volatile memory array. A reference current is connected to a leakage detection circuit. A reference code is determined for the leakage detection circuit coupled to a switching circuit. The reference code establishes a leakage current threshold. The reference current is disconnected from the leakage detection circuit and the switching circuit. Next, the leakage detection circuit is connected to a set of word lines of a storage block of a non-volatile memory array by way of the switching circuit. A memory current is generated within the set of word lines. A leakage code is determined for the set of word lines representing leakage current from the word lines in response to the memory current. The leakage code is compared with the reference code. If the leakage code exceeds the reference code, the storage block is deemed unusable.

  • Patent number: 11114178
    Abstract: Technology for physical defect detection in an integrated memory assembly having a control semiconductor die and a memory semiconductor die is disclosed. The control die compares actual current usage during a memory operation (such as a program operation) with expected current usage. In the event that the actual current usage deviates from the expected current usage by more than a threshold, a region of the memory structure is suspected as having a physical defect. For example, the selected word that is connected to the memory cells that were programmed may be suspected as having a physical defect. If a region is suspected as having a physical defect, a data integrity check may be performed in that region. If the data integrity check fails, the region may be marked as ineligible to store data.

The detectors monitor voltage levels and alert the processor if a droop event has been detected in real time. Multiple droops can be detected simultaneously, with each detected droop event generating an alert that is sent to a processor module, such as a clock control module, to act based on the detected droop. Each detector employs a ring oscillator that generates a periodic signal and a corresponding count based on that signal, where the frequency of the signal varies based on a voltage at the corresponding point being monitored.

  • Patent number: 10615641
    Abstract: Induction powered electrical current monitoring, and related devices, apparatuses, systems, and methods are disclosed. An electricity current monitoring device can include an inductive energy transfer medium, an energy storage device, a power management circuit, and a processing circuit. The inductive energy transfer medium can induce an electromotive force to produce electrical energy that can be stored in the energy storage device. A power management circuit can control storage of the electrical energy in the energy storage device and can control release of the electrical energy from the energy storage device. The processing circuit can measure the electrical current in the monitored energy source based on the fluctuating magnetic field generated by the inductive energy transfer medium. The processing circuit is electrically coupled to the power management circuit to be powered using the electrical energy released from the energy storage device.

  • Patent number: 10514400
    Abstract: A method for monitoring power used by a power monitoring system is provided. The method includes receiving preset information that defines periods in which one or more preset electric devices are scheduled to operate, and obtaining a power use rate indicating how much power is used in each period. Further, the method includes generating an alternative instruction to decrease estimated power consumption in a target period in which the power use rate increases. The estimated power consumption is estimated power consumption in the building in the target period in which the power use rate increases, using power consumption information, to which power consumption of the electric devices to be preset is registered in advance, and the preset information. The alternative instruction is displayed on a display of a terminal apparatus.

  • Patent number: 10429429
    Abstract: In a differential protection method for monitoring a line of a power grid, current indicator measured values are measured at the ends of the line and are transmitted to an evaluation device. A differential current value is formed with current indicator measured values temporally allocated to one another. The time delay between local timers of the measuring devices is used for the temporal allocation of the current indicator measured values measured at different ends. A fault signal indicating a fault affecting the line is generated if the differential current value exceeds a predefined threshold value. A check is carried out using electrical measured quantities temporally allocated to one another and a line-specific parameter to determine whether the time delay information indicates the actual time delay between the respective local timers. A time error signal is generated if erroneous time delay information is detected.

  • Patent number: 10418201
    Abstract: An intelligent electronic device (IED) may provide point on wave switching. The IED may receive a control operation request, and determine when to issue a control command to cause a switch to change positions. The actuation of the switch may occur at a target point on an alternating current. An IED may have a processor that is too slow to implement a switch when a desired point on an alternating current first occurs. Accordingly, some embodiments may compensate for the processing speed of an IED by determining a number of processor cycles needed (in advance) to issue a control command so that the resulting action results in the desired point on wave open or close.

Initially, a simulator transient analysis is performed on circuit blocks of a circuit design to obtain a current through each device path in each circuit block, and using the current obtained the IR drop and EM problems are examined to get EM-IR drop analysis. Next, a simulator transient analysis is performed on a top level circuit of a circuit design and current values generated in a first step to obtain EM-IR drop analysis for a full circuit design such that a circuit designer may debug, analyze and visualize various IR and EM value plots for circuit blocks and top level circuit of the circuit design together or separately.

  • Patent number: 10254346
    Abstract: A State of Charge (SOC) estimation device is provided for a secondary battery in which a correlation curve indicating a relationship between an SOC and Open Circuit Voltage (OCV) differs between a charging process and discharging process. The SOC estimation device estimates the SOC based on a relational formula in which as measured OCV increases, weights are assigned to the correlation curve for the discharging process, and as the measured OCV decreases, weights are assigned to the correlation curve for the charging process. Thus, the SOC estimation device provides accurate SOC estimates regardless of whether the secondary battery is being used or not.
