FLASH MEMORY SYSTEM AND CONTENTS-BASED BLOCK MANAGEMENT METHOD THEREOF

摘要

PURPOSE: A flash memory system and a contents-based block management method thereof are provided to manage blocks by using a contents-based list in order to reduce a mount time and efficiently manage a wear ratio. CONSTITUTION: A RAM(Read Random Memory)(120) loads a contents-based file system operated by a processing unit(110), and a flash memory(140) includes the blocks managed by the contents-based file system. If a file writing operation is requested, the contents-based file system selects one of blocks. The contents-based file system determines the kinds of the selected blocks as one of a pure block, a mixed block and a free block. The contents-based file system stores block type information and writing requested file at the block.
