Waiting for the data transmission to be completed, causing inconvenience to the user. To improve the speed of data transmission, only the old storage device can be eliminated, and a storage device with a larger capacity random access memory can be re-purchased to enhance the data. The speed of transmission will cause the user to waste money, and the storage devices that are eliminated will also cause environmental problems.

Therefore, how to develop a storage device that can improve the memory unit of the conventional technology, which is a lack of the conventional technology, is an urgent need for research and development.

The main purpose of the present invention is to provide a storage device for an expandable memory unit, which is provided by a expansion slot to provide a memory unit that is replaceably provided, so that the storage device The capacity of the memory unit is expanded. When the conventional storage device needs to read and write a large amount of data, the speed of data transmission is greatly reduced due to the limitation of the size of the random access memory, so that it takes more time to wait for the data. The transmission is completed, causing inconvenience to the user, unless a storage device with a larger capacity memory unit is re-purchased to increase the speed of data transmission, which will cause a waste of money for the user, and the storage device that is eliminated It will also cause environmental problems and other problems.

In order to achieve the above objective, a more general implementation of the present invention provides a storage device for an expandable memory unit electrically connected to a motherboard of a computer for storing digital data, including at least: a storage unit; a circuit a board connected to the storage unit and having a connection interface, a controller and a first memory unit; and an expansion slot disposed on the circuit board to provide a replaceable second memory Body unit settings.
