STORAGE DEVICE INCLUDING AUXILIARY POWER SUPPLY AND METHOD OF OPERATING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17876077 titled 'STORAGE DEVICE INCLUDING AUXILIARY POWER SUPPLY AND METHOD OF OPERATING THE SAME

Simplified Explanation

The patent application describes a storage device that includes a main system, a power loss protection integrated circuit (PLP IC), and an auxiliary power supply. The PLP IC provides power to the main system based on external or internal power, and the auxiliary power supply provides internal power to the PLP IC.

  • The main system can operate in a dump mode where data is backed up in response to specific conditions being met.
  • The PLP IC provides output power based on the internal power in the event of a sudden power off (SPO) occurring.
  • The first condition for data backup is when an SPO occurs and the SPO time is longer than a maximum filtering time.
  • The second condition for data backup is when an SPO occurs and the voltage level of the internal power provided by the auxiliary power supply is lower than a threshold voltage.

Potential Applications

  • This technology can be applied in various storage devices such as hard drives, solid-state drives, and other data storage systems.
  • It can be used in servers, data centers, and cloud storage systems to ensure data integrity and protection during power outages or sudden power losses.

Problems Solved

  • The technology addresses the problem of data loss or corruption that can occur during sudden power outages or losses.
  • It provides a solution for maintaining power supply to the main system and protecting data during power interruptions.

Benefits

  • The storage device with this technology ensures that data is backed up and protected even during sudden power losses.
  • It improves data reliability and integrity by preventing data loss or corruption.
  • The technology enhances the overall performance and reliability of storage systems, reducing the risk of data loss and downtime.


Original Abstract Submitted

A storage device includes a main system; a power loss protection integrated circuit (PLP IC) configured to provide output power to the main system based on external or internal power; and an auxiliary power supply configured to provide the internal power to the PLP IC. The main system may operate in a dump mode where data is backed up in response to at least one of a first condition or a second condition being satisfied. The PLP IC may provide the output power based on the internal power in response to a sudden power off (SPO) occurring. The first condition is satisfied when the SPO occurs and an SPO time is longer than a maximum filtering time. The second condition is satisfied when the SPO occurs and a voltage level of the internal power provided by the auxiliary power supply is lower than a voltage level of a threshold voltage.
