A volatile storage device and a serial mixed storage system having the same are provided. The system includes an access controller, a data transmission interface, a volatile storage module, a power supply module, an expansion interface and a non-volatile storage module. The volatile storage module and non-volatile storage module are connected in series via the expansion interface. The volatile storage module and the non-volatile storage module can be used to store data under the control of the access controller. Further, the power supply module can supply the stored electric power to the access controller, volatile storage module, and non-volatile storage module, so as to keep data stored in the volatile storage module or transfer the data to the non-volatile storage module, thereby avoiding data loss caused by power cutoff.
