Patent attributes
A memory module and a method of performing the same for access of an external electronic device are provided herein. The memory module includes a NAND-type flash memory, a dynamic random access memory (DRAM) unit, and a memory controller. The dynamic random access memory unit which is electrically connected to the NAND-type flash memory includes a dynamic random access memory and an internal power. The memory controller is used for controlling at least one of both the NAND-type flash memory and the dynamic random access memory unit. When the memory module is disconnected with the external electronic device, the internal power of the dynamic random access memory unit powers the dynamic random access memory, actively. Accordingly, data stored in the dynamic random access memory will be retained.
