摘要： A data access method capable of reducing the number of erasing to flash memory and a data patch and access device that utilizes the method are disclosed. A data write procedure is provided for determining a difference between data to be written and existed data in the data block when writing data to a data block of the flash memory, and if the difference is less than a pre-determined value, writing the difference to a patch area instead of writing the data to the data block. A data read procedure is provided for searching the difference recorded in the patch area when reading data from a data block of the flash memory, so as to patch the data.

摘要： A flash memory device with a wear-leveling mechanism includes at least one flash memory, a hot list, a bitmap, a source pointer, and a controller. The controller obtains a physical memory block with high erase count through the hot list, an erase count of the physical memory block, and an overall average erase count of the flash memory device. The controller further finds out a physical memory block which stores static data through managing the bitmap and the source pointer. The controller moves the static data to the physical memory block with high erase count, and releases the physical memory block which stores the static data to avoid the physical memory block with high erase count being worn down increasingly more seriously.

摘要： 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.
