Abstract: An automatic updating method is applied to an electronic device storing an operating system. The operating system includes a first header. The electronic device is electrically connected to a memory device selectively. The automatic updating method includes the following steps. First, whether the electronic device is electrically connected to the memory device is nonstop determined. Then, when the electronic device is electrically connected to the memory device, whether an updating file is stored in the memory device is determined. After that, when the updating file is stored in the memory device, a second header of the updating file is read. Then, whether the first header and the second header are identical is determined. After that, when the first header and the second header are not identical, the updating file is read to update the operating system.

Abstract: A memory partitioning method is applied in a memory module having a plurality of physical blocks. The partitioning method includes the following steps. First, a partitioning command is received. Next, at least one first memory driving module and a second memory driving module are called according to the partitioning command. Then, at least one location code corresponding to one of the physical blocks is obtained according to the first memory driving module and/or the second memory driving module, and the physical blocks are divided into a first memory area and a second memory area according to the location code. Finally, the first memory driving module and the second memory driving module respectively partition the first memory area and the second memory area.
