1. Research goal
- Provides the maximum capacity of MLC flash memory
- Provides the performance and endurance close to SLC flash memory
2. Our approaches
- Exploit a flexible cell programming of MLC flash memory
- Write data into SLC region and migrates them to MLC region using idle time
- Adjust the amount of data to be written to SLC region considering performance and lifetime
3. Published papers
