Embodiment Construction
[0053] Please refer to figure 1 , figure 1 It is a schematic diagram of a memory device 100 according to a first embodiment of the present invention, wherein the memory device 100 of this embodiment is especially a portable memory device (for example: a memory card conforming to SD / MMC, CF, MS, XD standards ). Memory device 100 includes: a flash memory (FlashMemory) 120; The error correction capability of the memory controller 110) can be improved without increasing the number of encoding / decoding bits of the Error Correction Code Engine (ECC Engine). According to the present embodiment, the memory controller 110 includes a microprocessor 112 , a read only memory (ROM) 112M, a control logic 114 , a buffer memory 116 , and an interface logic 118 . The ROM is used to store a program code 112C, and the microprocessor 112 is used to execute the program code 112C to control access to the flash memory 120 . Please note that the program code 112C may also be stored in the buffer ...
