Abstract:
In a case where at least one of physical blocks composing the virtual block becomes a defective block, use of the virtual block to which the defective block belongs is forbidden and the virtual block of which use is forbidden is managed as a defective virtual block. Replacing the defective block with a normal block is performed among the defective virtual blocks so as to generate the virtual block to which the defective block does not belong. Then use of the virtual block generated is allowed.
