Exploiting Data Longevity for Enhancing the Lifetime of Flash-based Storage Class Memory

Exploiting the Interplay Between Memory and Flash Storage for Sensor Data Management

Although memory is an important constraint in embedded sensor nodes, existing sensor applications and systems are typically designed to work under the memory constraints of a single platform and do not consider the interplay between memory and flash storage. In this paper, we present the design of a memory-adaptive flash-based sensor system that allows an application to exploit the presence of ...

Data Management in a Flash Memory Based Storage Server

Flash memory has many attractive features, such as nonvolatility, light weight, and low power consumption. These features show promise for using flash memory as storage in consumer electronics, embedded systems, and mobile computers. However, flash memory has specific hardware characteristics that impose challenges on the design of storage systems. It cannot be overwritten unless erased in adva...

Extending flash lifetime in secondary storage

Unlike magnetic disks, NAND flashes can be written a limited number of times. As flash memory densities increase and cell sizes shrink, further decreases in write endurance is expected. Although some mitigation is achieved by wear leveling, write endurance remains a concern for write intensive applications. In this research, we use a DRAM cache to filter write traffic to flash by coalescing and...

Flash Memory Management for Lightweight Storage Systems1

This report describes a management scheme for flash memory-based storage systems. This scheme will be implemented into a flash memory-based FAT file system in the Ramos project running in the Institute of Information Science (IIS). Ramos project targets on building software components for real time and multimedia applications that most of the consumer electronic products can be easily construct...
