Flash Memory System

1.Research goal & our approaches 

- Evaluate existing Hot/Cold separator using the oracle predictor on future update time


- Knowing future update time is an important factor in separating data


- Propose a new data separation technique based on update times of data




- Predicts indirectly update times of data based on program behavior


- Some parts of a program repeatedly have similar behavior patterns


- Separates data based on characteristics of each program contexts
