Abstract
Recently, as the capacity of flash memory increases rapidly, efficient indexing methods become crucial for fast searching of a large volume of data stored in flash memory. Flash memory has its unique characteristics: the write operation is much more costly than the read operation and in-place updating is not allowed. In this paper, we propose a novel index structure that significantly reduces the number of write operations and thus supports efficient searches, insertions, and deletions. We verify the superiority of our method by performing extensive experiments.
