RIFFS: Reverse Indirect Flash File System

Abstract

This project presents a new technique for flash storage management called a Reverse-Indirect Flash File System (RIFFS). However, flash memories have a drawback: its data cannot be updated-in-place. To solve this limitation, the data is stored inside of the proper file. The solution was to construct a reverse-tree. This would be impracticable with the current systems, because it would not be possible to locate a file directly, from root directory. This schema would break the navigability of the system, and then a direct tree need to be constructed in RAM memory. This article shows the reverse-tree management schema to solve the limitations of flash memories. This solution helped to minimize extreme updates and write operations, increasing flash life-time. © Springer-Verlag Berlin Heidelberg 2004.
