Classification: CPC G | IPC G

Claim 0:
1. A dummy dual in-line memory module testing system based on a boundary scan interconnect, comprising:
a dummy dual in-line memory module, served as a test fixture, wherein all functions of the test fixture are normal;
a dummy dual in-line memory module under test, served as a unit under test;
a test access port (TAP) device, connected to a terminal machine executing a test program, wherein the test access port (TAP) device comprises signal pins and is configured to transmit a control signal and receive a data signal through the signal pins, wherein the signal pins comprise a test data in pin, a test data out pin, a test clock pin, and a test mode select pin; and
a test device, electrically connected to the test access port (TAP) device through the signal pin, and comprising:
a first slot, configured for insertion of the dummy dual in-line memory module to electrically connect the dummy dual in-line memory module to the test device;
a second slot, configured for insertion of the dummy dual in-line memory module under test to electrically connect the dummy dual in-line memory module under test to the test device;
a power supply module, connected a DC power supply, wherein when the test program performs a test, the power supply module makes the DC power supply continuously supply power to the first slot and the second slot, and when the test is finished, the power supply module makes the DC power supply stop supplying power to the first slot and the second slot; and
a transmission module, configured to receive the control signal from the test access port (TAP) device, to control the test fixture to test the unit under test through the boundary scan, wherein when the test program is executed, the transmission module transmits the data signal, which is collected from at least one boundary scan register, to the test access port (TAP) device through the signal pin, to check a test result.
