Abstract
A highly efficient data characteristic identification device for flash memory is provided, including an instruction register, a plurality of auxiliary controllers, a data register, an address register, a microprocessor, a plurality of hash function units, a hash table unit, a comparator, a shifter, and an adder. By connecting the instruction register, data register and address register to a flash memory access control circuit and flash memory for storing the control instruction of the access control circuit and the data and physical and logical address of the flash memory, the control instruction is decoded and transmitted by the microprocessor and the auxiliary controllers to each circuit. A plurality of hash function units, a hash table unit, a comparator, a shifter, and an adder form an index computation circuit for flash memory LBA. By using the index and computation on the contents of the hash function units, the data characteristics of the LBA can be stored with less memory and higher efficiency. Therefore, the object of a highly efficient data access characteristic identification device for flash memory is provided.
