Abstract

Flash memory becomes ideal storage media for small size embedded systems as well as for large size multimedia applications because of its attractive features like fast access speed, shock resistance, high reliability and further more it's rapidly increasing capacity. However, flash needs expensive erase operations for rewriting data on same memory locations that degrades the system performance. Therefore, for increasing performance by decreasing the number of erase operations, data in flash memory is likely to be handled by access patterns in hot and cold data nature categories. Separately storing data by nature in different blocks however reduces the frequent erasures but as a side effect consumes large main memory space to maintain the memory mapping table at fine granularity on a page level. In this paper, an innovative storage management framework is proposed where data is stored by nature in separate physical blocks but mapping structures are retained at coarse granularity on a block level. Simulation results using real time traces ensure significantly improved overall system performance with 70.5% and 42% reduced erasures, and 39.33 minutes preserved migration cost compared to well known previous schemes.

Reviews

Reviewer: Elliot Jaffe

Rizvi and Chung attempt to use block access patterns to improve flash memory storage performance. In such file systems, the operating system divides each file into blocks, usually consisting of 4 kilobytes (KB). The flash memory operates at the level of 512-byte pages. The proposed system optimizes the allocation of pages to blocks so that active (hot) blocks require minimal updating of data structures on the drive, resulting in faster performance and lower wear on the physical file system. Unfortunately, the writing in this paper is extremely difficult to follow. The authors struggle with the English language, and write very tersely. If you read this paper, prepare to spend a lot of time deciphering the text for the kernels of new ideas contained within. Online Computing Reviews Service
