COMPUTING SYSTEM INCLUDING PHASE CHANGE MEMORY DEVICE

摘要

PURPOSE: A computing system including a phase changing memory is provided to store an address mapping table necessary for managing a flash memory in a phase changing memory, thereby improving speed and lifetime of the computing system. CONSTITUTION: A flash memory(140) stores data. A phase changing memory(130) stores address mapping information for changing a logical address into a physical address. The phase changing memory stores the address mapping information during power-off of a computing system. The address mapping information defines correspondence relation between the physical address and the logical address.
