Embodiment 1
[0067] figure 1 It is the data storage system shown in Embodiment 1 of the present invention.
[0068] Please refer to figure 1 , the data storage system 300 includes a flash storage device 100 , a computer host 200 , and a pattern analysis unit 150 . The flash storage device 100 is connected to the host computer 200 so that the host computer 200 can write data into the flash storage device 100 or read data from the flash storage device 100 . In this embodiment, the flash storage device 100 is a solid state drive (SSD). But it must be understood that in another embodiment of the present invention, the flash memory storage device 100 can also be a memory card or a flash drive. In addition, in this embodiment, the pattern analysis unit 150 is realized by being installed in the host computer 200 in the form of software. However, the pattern analysis unit 150 can also be implemented in a firmware form or a hardware form.
[0069] The flash storage device 100 includes a flash c...
Embodiment 2
[0113] Figure 4 It is a data storage system according to Embodiment 2 of the present invention.
[0114] Please refer to Figure 4 , the data storage system 400 includes a flash memory module 410 and a flash memory controller 420
[0115] The data storage system 400 is detachably connected to the host system 600 so that the host system 600 can write data into the data storage system 400 or read data from the data storage system 400 . In this embodiment, the data storage system 400 is a solid state drive (SSD). But it must be understood that, in another embodiment of the present invention, the data storage system 400 may also be a memory card or a flash drive.
[0116] The flash memory module 410 includes a control circuit 412 and physical blocks 414-0˜414-N.
[0117] The control circuit 412 is used to transmit data to the physical blocks 414 - 0 - 414 -N or read data from the physical blocks 414 - 0 - 414 -N according to the instructions of the flash memory controller 420...
