MEMORY SYSTEM FOR BACKING UP DATA IN CASE OF SUDDEN POWER-OFF AND OPERATION METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18054196 titled 'MEMORY SYSTEM FOR BACKING UP DATA IN CASE OF SUDDEN POWER-OFF AND OPERATION METHOD THEREOF
Simplified Explanation
The patent application describes a memory system that includes different types of memory devices and a memory controller. When there is a sudden power-off, the memory controller transfers user data from a volatile memory device to a faster non-volatile memory device. Here are the key points:
- Memory system with different types of memory devices and a memory controller.
- Volatile memory device stores user data or a map table.
- Non-volatile memory devices are used for data storage.
- Memory controller transfers user data from volatile memory to a faster non-volatile memory in case of sudden power-off.
- The first non-volatile memory device has faster write speed and smaller capacity compared to the second non-volatile memory device.
Potential applications of this technology:
- Computer systems and servers that require reliable data storage in case of power failures.
- Embedded systems and IoT devices that need to preserve data during unexpected power interruptions.
- Mobile devices and tablets that can quickly save user data when the battery is about to die.
Problems solved by this technology:
- Data loss due to sudden power-off events.
- Slow data transfer from volatile to non-volatile memory devices.
- Limited capacity of faster non-volatile memory devices.
Benefits of this technology:
- Enhanced data reliability and integrity during power failures.
- Faster data transfer and improved system performance.
- Efficient utilization of different types of memory devices.
Original Abstract Submitted
A memory system includes a first non-volatile memory device, a second non-volatile memory device, at least one volatile memory device configured to store user data or a map table, and a memory controller configured to data-dump the user data from the at least one volatile memory device to the first non-volatile memory device when a sudden power-off occurs. The first non-volatile memory device has a faster speed at which data is written than the second non-volatile memory device and has a smaller capacity than the second non-volatile memory device.
