Abstract
A flash memory accessing apparatus is disclosed. The flash memory accessing apparatus includes a memory controller, a first open NAND flash interface (ONFI) and an expanding flash memory module. The first ONFI is used for connecting a main flash memory module. The memory controller obtains a detecting result by, detecting whether the main flash memory module and the expanding flash memory module are single side or double side. The memory controller further configures an accessing method of the main flash memory module and the expanding flash memory module according to the detecting result.
Claims16
A flash memory accessing apparatus, comprising:
- a memory controller;
- a first open NAND flash interface (ONFI), coupled to the memory controller for connecting a main flash memory module;
- and
- an expanding flash memory module, coupled to the memory controller and the first ONFI,
- wherein the memory controller obtains a detecting result by detecting whether the main flash memory module connected to the first ONFI and the expanding flash memory module are single side or double side, and configures an accessing method of the main flash memory module and the expanding flash memory module according to the detecting result.
A flash memory accessing method, comprising:
- providing a first ONFI to connect a main flash memory module;
- providing an expanding flash memory module;
- providing a memory controller for detecting whether the main flash memory module connected to the first ONFI and the expanding flash memory module are single side or double side to obtain a detecting result;
- and
- providing a memory controller for configuring an accessing method of the main flash memory module and the expanding flash memory module according to the detecting result.
