In this paper, we propose a new log buffer management scheme considering the accessibility of the data. Our proposed method evaluates the worth of the merge of log blocks. It conducts the merge operations between infrequently updated data and the data blocks and postpones as much as possible the merge operations between frequently updated data and the data blocks. As a result, the proposed method prevents the unnecessary merge operations, reduces the number of the erase operations, and improves the utilization of the flash memory storage. It is shown through performance evaluation that the proposed method outperforms BAST and FAST.
