HIERARCHICAL MEMORY ARCHITECTURE TO CONNECT MASS STORAGE DEVICES

摘要

PURPOSE: A hierarchical memory architecture for connecting a storage device including a collecting device within a memory storage system is provided to improve memory storage effect through hierarchical data storage in a hierarchical memory architecture. CONSTITUTION: A concentrator(30) includes a front side bus port to a backside port and a processor front side bus. A data stored in external memory devices is received to the backside port. The data is stored in a PCM(Pulse Code Modulation) array. The data is transmitted through the front side bus port to a processor(20). The external memory device is arranged after the concentrator.
