Abstract: Aiming at the disadvantage of continual access and life limitation of flash memory in some mass storage system, this paper propose a high performance Flash/FRAM hybrid architecture data storing system and bring forward storage scheme which the system log area, file index table and real time data are storaged in FRAM, whereas the bulk historical data are in Flash.It also provide a system structure and implementation method.Experimental results show this hybrid architecture effectually improve the access efficiency and reliability.
