Abstract

Non-volatile memory control method and apparatus, where divides the non-volatile memory by the erasing unit, and installes the area that stores the block managing information, in the same block. The said apparatus consists of a storage area that stores the block managing information in the divided block, a managing information writing means, and a volatile memory that stores the managing information.
