| Abstract: | Recently, a flash memory has become a major database storage in building portable information devices because of its non-volatile, shock-resistant, power-economic nature, and fast access time for read operations. We propose a new scheme called flash memory shadow paging (FMSP) for efficient page management in a flash memory database environment. We improved traditional shadow paging schemes by reusing old data pages which are supposed to be disposed in the course of writing a new data page in the flash memory file systems. In order to reuse these data pages, we devised a deferred cleaning procedure and an operation interface which is geared to existing flash file systems. FMSP contributes to overcome the two drawbacks of traditional shadow paging schemes, additional space overhead and slow access caused by old page management. We also propose a simulation model to show the performance of FMSP. Based on the results of the performance evaluation, we conclude that FMSP scheme outperforms the traditional shadow paging schemes.
