摘要：
A storage has a first cache area temporarily storing one page data read from a flash memory, and a second cache area to which data of the first cache area is transferred. A controller stores data of the first cache area in the second cache area, and reads and outputs the data stored in the second cache area when data having the same address as data read from the first cache area is read.
