Detection and Isolation of Faulty Holdup Capacitors Using Hardware Circuit in Data Storage Devices - A simplified explanation of the abstract

This abstract first appeared for US patent application 17852103 titled 'Detection and Isolation of Faulty Holdup Capacitors Using Hardware Circuit in Data Storage Devices

Simplified Explanation

The patent application describes systems and methods for detecting and isolating faulty hold-up capacitors in a data storage device, and performing corrective actions. Here is a simplified explanation of the abstract:

  • A hardware circuit is connected to a micro-controller and non-volatile memory dies.
  • The hardware circuit provides backup power for the memory and micro-controller.
  • The method detects if a hold-up capacitor in the hardware circuit is faulty.
  • If a faulty capacitor is detected, it is isolated from the circuit.
  • The micro-controller obtains the status of an interface connected to the hardware circuit.
  • Based on the interface status, the micro-controller determines the status of the hardware circuit.
  • If one or more faulty capacitors are detected, the micro-controller performs corrective actions for the data storage device.

Potential applications of this technology:

  • Data storage devices such as hard drives, solid-state drives, and memory cards.
  • Any electronic device that requires backup power and uses hold-up capacitors.

Problems solved by this technology:

  • Faulty hold-up capacitors can cause power issues and data loss in data storage devices.
  • Detecting and isolating faulty capacitors ensures reliable backup power and prevents data corruption.

Benefits of this technology:

  • Improved reliability and performance of data storage devices.
  • Prevents data loss and corruption due to faulty capacitors.
  • Allows for timely corrective actions to be taken to maintain the functionality of the device.


Original Abstract Submitted

Disclosed are systems and methods detecting and isolating faulty hold-up capacitors and performing corrective actions for a data storage device. A hardware circuit is coupled to a micro-controller and non-volatile memory dies. The method includes, at the hardware circuit: providing a back-up power for the non-volatile memory dies and the micro-controller; and detecting whether a hold-up capacitor of the hardware circuit is faulty and isolating the hold-up capacitor in accordance with a detection that the hold-up capacitor is faulty. The method also includes, at the micro-controller: obtaining a status of an interface coupled to the hardware circuit; determining a status of the hardware circuit based on the status of the interface; and performing a corrective action for the data storage device in accordance with a determination that the status of hardware circuit corresponds to one or more faulty hold-up capacitors.
