METHOD OF OPERATING STORAGE DEVICE FOR RETENTION ENHANCEMENT AND STORAGE DEVICE PERFORMING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17872162 titled 'METHOD OF OPERATING STORAGE DEVICE FOR RETENTION ENHANCEMENT AND STORAGE DEVICE PERFORMING THE SAME
Simplified Explanation
The abstract describes a method for operating a storage device that includes a storage controller and a nonvolatile memory. Here is a simplified explanation of the abstract:
- The storage device is powered on when an external power supply voltage is activated.
- The device waits for communication to be established with a host device based on a link signal between the storage device and the host device.
- If communication is not established, a retention enhancement operation is performed on the storage device.
- The retention enhancement operation involves entering a retention enhancement mode and providing at least one command from the storage controller to the nonvolatile memory.
Potential Applications:
- This method can be applied in various storage devices such as solid-state drives (SSDs), USB flash drives, and memory cards.
- It can be used in devices that require efficient power management and data retention, such as mobile phones, laptops, and IoT devices.
Problems Solved:
- Ensures efficient power management by powering on the storage device only when the external power supply voltage is activated.
- Addresses the need for reliable communication between the storage device and the host device by waiting for the establishment of communication.
- Improves data retention in the storage device by performing a retention enhancement operation when communication is not established.
Benefits:
- Efficient power management helps in conserving battery life and reducing energy consumption.
- Reliable communication ensures proper functioning and data transfer between the storage device and the host device.
- Enhanced data retention improves the reliability and longevity of the storage device, reducing the risk of data loss.
Original Abstract Submitted
In a method of operating a storage device including a storage controller and a nonvolatile memory, the storage device is powered on based on an activation of an external power supply voltage. An establishment of communication with a host device is waited for, based on a link signal between the storage device and the host device. Without the establishment of communication with the host device, a retention enhancement operation is performed on the storage device by entering a retention enhancement mode and by providing at least one command from the storage controller to the nonvolatile memory.
