Example Embodiment
[0024] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments accompanied with drawings are described in detail below.
[0025] Since the previous technology used to prevent damaged blocks from being used by users, the addresses of all storage blocks are mapped in advance to exclude damaged blocks, which requires a lot of memory to manage, which increases a lot of unnecessary hardware costs. . Therefore, the present invention provides a flash memory control device and method. With a small amount of hardware cost, it is also possible to "prevent damaged blocks from being used by users". The detailed implementation will be described in the following examples.
[0026] FIG. 2 is a circuit block diagram of a flash memory control device according to an embodiment of the present invention. Please refer to FIG. 2. The circuit block diagram of this embodiment includes an interface circuit 200, a controller ...
