Abstract: In view of the working principle and physical characteristics of NAND Flash devices, mass solid state memory system can introduce multi-channel parallel technology to support high-speed data transmission.This paper proposes a new addressing method for Flash Array Storage System-FVLA (Flash Virtual Layer Address), which can well reflect the operation sequence of flash memory system and can be configured flexibly.This paper uses the addressing mode to design an address mapping method based on superpage. The simulation results show that the mapping method can perform parallel operations and greatly reduce the memory space occupied by the mapping table.
