Abstract: A management method for reducing the utilization rate of random access memory (RAM) while reading data from or writing data to the flash memory is disclosed. A physical memory set is constructed from a plurality of physical memory blocks in the flash memory. A logical set is constructed from a plurality of logical blocks wherein the data stored in the logical set are stored in the physical memory set. Further, the data stored in each of the logical blocks are stored in one number of physical memory blocks. A mapping table is constructed and includes a hash function, a logical set table, a physical memory set table, and a set status table for managing the relationship among the physical memory sets, physical memory blocks, and logical blocks while reading data from or writing data to the flash memory.
