ABSTRACT:
An allocating method for a flash memory is disclosed. The allocating method includes the following steps: adjusting a preliminary data storage capacity corresponding to the flash memory for determining a real data storage capacity of the flash memory; adjusting a preliminary spare area capacity corresponding to the flash memory for determining a real spare area capacity of the flash memory, wherein a total capacity of the preliminary data storage capacity and the preliminary spare area capacity is equal to the total capacity of the real data storage capacity and the real spare area capacity; and allocating the real data storage capacity and the real spare area capacity to the flash memory, wherein the real data storage capacity stores data, and the real spare area capacity stores parity codes generated by an error codes correction algorithm performed upon the stored data in the real data storage capacity.
