ABSTRACT:
The present invention provides a method for accessing a memory device and a memory accessing device. The method includes a) providing the memory device having a plurality of memory sub-spaces respectively having a plurality of address ranges; b) respectively assigning a plurality of base addresses to the plurality of memory sub-spaces; c) inputting an access address; d) respectively operating the base addresses with the access address to obtain a plurality of operated results; and e) accessing one of the memory sub-spaces if a specific one of the operated results falls within one of the address ranges corresponding to the one memory sub-space. The memory accessing device includes an access address end, a data access end, an access selection end, a memory device having a plurality of memory sub-spaces, and a plurality of access devices respectively electrically connected to the memory sub-spaces, and each of which includes a base address storing device for storing therein a base address, an operating and comparing device for operating the access address with the base address to obtain an operated result and generating a data access enabling signal when the operated result falls within an address range, and a data buffer for accessing the respective memory sub-space in response to the data access enabling signal and the access selection signal.
