Recent years have witnessed a proliferation of ash memories as an emerging storage technology with wide applications in many important areas. Like magnetic recording and optimal recording, ash memories have their own distinct properties and usage environment, which introduce very interesting new challenges for data storage. They include accurate programming without overshooting, error correction, reliable writing data to ash memories under low-voltages and file recovery for ash memories. Solutions to these problems can significantly improve the longevity and performance of the storage systems based on ash memories.

520 $a Recent years have witnessed a proliferation of ash memories as an emerging storage technology with wide applications in many important areas. Like magnetic recording and optimal recording, ash memories have their own distinct properties and usage environment, which introduce very interesting new challenges for data storage. They include accurate programming without overshooting, error correction, reliable writing data to ash memories under low-voltages and file recovery for ash memories. Solutions to these problems can significantly improve the longevity and performance of the storage systems based on ash memories.
520 $a In this work, we explore several new data representation techniques for efficient and reliable data storage in ash memories. First, we present a new data representation scheme---rank modulation with multiplicity ---to eliminate the overshooting and charge leakage problems for ash memories. Next, we study the Half-Wits---stochastic behavior of writing data to embedded ash memories at voltages lower than recommended by a microcontroller's specifications---and propose three software-only algorithms that enable reliable storage at low voltages without modifying hardware, which can reduce energy consumption by 30%. Then, we address the file erasures recovery problem in ash memories. Instead of only using traditional error- correcting codes, we design a new content-assisted decoder (CAD) to recover text files. The new CAD can be combined with the existing error-correcting codes and the experiment results show CAD outperforms the traditional error-correcting codes.
