MEMORY APPARATUS FOR COLLECTIVE VOLUME MEMORY AND METADATE MANAGING METHOD THEREOF

摘要

PURPOSE: A memory device for the bulk unified memory, and a meta-data managing method are provided to minimize the saving space overhead of meta-data in a local node and a master node for the bulk unified memory. CONSTITUTION: A memory device for the bulk unified memory comprises the following: a CVM(collective volume memory) command tool(210) for managing a CVM, and controlling the operation of the CVM by analyzing inputted commands from users; and a CVM engine(220) configuring the CVM, initializing, or allocating or accessing the CVM by data transferred from the CVM command tool.
