Memory comprising a chain with the link pointer to find a block having a block-erasable pointer information and the memory locations

摘要

Memory device is provided with a (10) main memory having a physical block of memory a large number of positions. Main memory, for example, flash memory, erasing the physical block of at least one at a time. Save (10) in the main memory finally, pointing to the pointing information, such as the logical address leading to physical address mapping table, the chain pointer (72 and 75), each pointer each block (the (72, 75) Save the brackets 70, 74), (72) is intended to refer to (74) corresponding block with a pointer to the next in the chain each pointer not the last in the chain. Startup main memory (10), using the pointer from the main memory, to find the pointing information through the chain. In normal operation, to be used preferentially direct pointer that is stored in RAM memory.
