STORAGE DEVICE INCLUDING AUXILIARY POWER SUPPLY DEVICE AND OPERATING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 17958668 titled 'STORAGE DEVICE INCLUDING AUXILIARY POWER SUPPLY DEVICE AND OPERATING METHOD THEREOF
Simplified Explanation
The patent application describes a storage device that includes a power supply device and a main system. The power supply device has an auxiliary power supply that provides auxiliary power and generates a deterioration monitoring signal indicating the degree of deterioration of the auxiliary power supply. It also generates an output voltage based on external power or the auxiliary power. The main system operates based on the output voltage and performs a dump operation to back up data in a sudden power off situation.
- The main system compares the degree of deterioration of the auxiliary power supply with a preset reference value in response to the deterioration monitoring signal.
- Based on the comparison result, the main system generates a voltage scaling command to control the power supply device.
- The voltage scaling command converts the average voltage level of the output voltage to a dynamic voltage scaling level.
Potential applications of this technology:
- Data storage devices such as hard drives or solid-state drives.
- Backup power systems for critical infrastructure or sensitive equipment.
Problems solved by this technology:
- Ensures data backup in sudden power off situations.
- Monitors and manages the deterioration of the auxiliary power supply.
Benefits of this technology:
- Improved reliability and data integrity in power loss scenarios.
- Efficient use of power by dynamically scaling the voltage level.
- Extended lifespan of the auxiliary power supply through monitoring and control.
Original Abstract Submitted
A storage device includes a power supply device including an auxiliary power supply device providing auxiliary power, configured to generate a deterioration monitoring signal indicating a degree of deterioration of the auxiliary power supply device, and configured to generate an output voltage based on external power or the auxiliary power; and a main system configured to operate based on the output voltage and perform a dump operation for backing up data in a sudden power off (SPO) situation, wherein the main system compares the degree of deterioration of the auxiliary power supply device with a preset reference value in response to the deterioration monitoring signal, and generates a voltage scaling command for controlling the power supply device to convert an average voltage level of the output voltage to a dynamic voltage scaling (DVS) level based on a result of the comparison.
