System and method for detecting memory faults

The invention discloses a system for detecting memory faults. The system is applied to detecting a double-data rate synchronous dynamic random memory (DDR); the system comprises a printed circuit board (PCB), a detection socket, a development test board and a detection module, wherein the PCB is connected to the development test board; the detection socket is connected to the PCB; the DDR is arranged on the detection socket; the detection module is connected with the development test board and used for detecting the DDR. According to the system for detecting the memory faults, the detection socket is adopted and the DDR can be welded on the socket and then is detected, and therefore, the traditional way of directly welding on the test board is avoided, the limitation that both CPU and DDR are packaged in a BGA can be broken through; besides, due to the adopted detection socket, the utilization rate of detection hardware can be increased and the cost of detecting the DDR is greatly reduced.
