| 摘要 |
A semiconductor memory module and a semiconductor memory device are disclosed. In one embodiment, the invention provides a semiconductor memory module comprising a circuit board, a plurality of semiconductor memory devices adapted to operate during a test mode and a normal operation mode and mounted on the circuit board, a first signal line set comprising a plurality of first signal lines connected to the plurality of semiconductor memory devices, and a plurality of second signal line sets. Each semiconductor memory device comprises first terminals adapted to receive first signals from the first signal lines, second terminals connected to a corresponding one of the second signal line sets, a third terminal adapted to receive an enable signal during the test mode, and a signal transmitting unit adapted to output second signals to the second terminals in response to the enable signal.
