Window-based flash memory storage system and management and access methods thereof

A reading method to a flash memory from a data-access requesting component, wherein the flash memory includes a plurality of storage sectors, and a read operation to one sector of the storage sectors needs a plurality of stages handled by an access controller, the reading method comprising:

• performing a first read operation to read a current sector of the storage sectors;
• starting to perform a second read operation to a next sector of the storage sectors when the first read operation is not completed yet;
• starting to perform a third read operation to read a further next sector of the storage sectors when the first read operation and the second read operation are not completed yet;
• and
• starting to perform a first stage of a third read operation to find out a further next sector of the storage sectors to be read when the first read operation and the second read operation are not completed yet,
• wherein the second read operation starts before the first read operation ends thereby decreasing the time required to perform read operations and increasing overall system performance,
• wherein the stages includes a first stage for finding a sector of the storage sectors to be read, a second stage for transmitting an information to be read from the flash memory into the access controller, and a third stage for transmitting an information to be read in the access controller into the data-access requesting component,
• wherein the third stage of the first read operation, the second stage for the second read operation, and the first stage for the third read operation are overlapping.
