Abstract: Methods for updating and recovering user data of a non-volatile memory array such as a flash memory are disclosed. An indication for indicating a mapping relationship for a logical address is established when original user data of the logical addresses is updated into new user data. The indication records new pointers, which record the mapping relationships between logical addresses and physical addresses storing the new user data of the logical addresses. Alternatively, the indication records memory positions of the non-volatile memory array which are defined as designated memory positions and a sequence for using these designated memory positions.

Abstract: A control unit accesses a memory. The memory includes a plurality of blocks. The control unit includes a batch buffer, a batch controller and a multiplexer. The batch buffer stores a batch which includes a designated block index. The batch controller fetches the designated block index from the batch buffer. The multiplexer selectively outputs a sequential block index or the designated block index as an active index according to a control signal. And a designated block of the memory is accessed according to the active index.
