Abstract
An address at which a writing error occurs is held, and after a completion of a series of writings, the data of the held address is read. Then, a faulty-block processing is performed only for the addresses, for which it is determined that retry of writing is required, thereby preventing an increase of faulty-blocks. This can suppress the problem that when a writing is performed in a particular flash memory, a writing error frequently occurs and a large number of faulty blocks occur.
