A network packet storage method and network packet transmitting apparatus using the same is provided. A packet content and a path control information are obtained from a received packet, and a packet storage address of the packet content is determined according to a predetermined storage rule. The packet content is stored in a data block and packet storage addresses and path control information of packets output via the same output port are stored in a control block. The data block is output when its size reaches a predetermined data block size such that a dynamic random access memory receives the data block by using burst mode. Further, the control block is output when its size reaches a predetermined control block size.
