Abstract

The invention provides a connection interface circuit, a signal transmission device and a memory storage device. The connection interface circuit is used for transmitting signals. The connection interface circuit comprises a first wire, a second wire, a first interface assembly and a second interface assembly. The first interface assembly is connected to a control circuit through the first wire. The second interface assembly is connected to the control circuit through the second wire. The length of the first wire is substantially the same as the length of the second wire. And the length configuration of the first wire and the second wire is matched with the transmission frequency band of the signal. Therefore, the signal transmitting and receiving quality of the connecting interface circuit with the plurality of interfaces can be improved.

Description

technical field [0001] The invention relates to an electronic circuit, and in particular to a connection interface circuit, a signal transmission device and a memory storage device. Background technique [0002] Some types of memory storage devices (such as USB flash drives) can be configured with multiple different types of external connection interfaces at the same time. The user can select an appropriate interface from these external connection interfaces to connect the external electronic device or connection line to the memory storage device according to the specifications of the electronic device or connection line to be connected at the moment, thereby improving the connection between the memory storage device and the external Compatibility when connected to electronic devices or cables. However, in a memory storage device configured with multiple different types of external connection interfaces, an additional switching circuit is often required to switch signal tra...
