(English Abstract)
Flash memory has its unique characteristics: i.e., (1) the write operation is much more costly than the read operation. (2) In-place updating is not allowed. In this paper, we first analyze how these characteristics affect the performance of record management in flash memory, and discuss the problems with previous methods for record management when they are applied to flash memory environment. Next, we propose a new record management method to be suitable for flash memory environment. The proposed method employs a new concept of a container that makes it possible to overwrite data on flash memory several times when performing insertions, deletions, and modifications of records. As a result, this method reduces the number of overwrite operations, and consequently does the number of erase operations. The results of experiments show that our method improves the performance by up to 34%, compared with the previous one.
