Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 7:
8. A chip detection apparatus, comprising:
a test module, configured to transmit a test signal to a chip to be tested so that the chip is in a preset working mode, the chip comprising a power pump region, and the power pump region comprising a plurality of power pump structures;
a detection module, configured to detect a dim light signal emitted from the power pump region when the chip is in the preset working mode; and
a determination module, configured to determine whether the dim light signal matches a corresponding power pump working mode in the preset working mode, and when not, confirm that the power pump region has a defect, the power pump working mode comprising a working state of the power pump structures in the power pump region;
wherein the preset working mode comprises a pre-charge working mode;
the test module is configured to transmit a second test signal to the chip, so that the chip is in the pre-charge working mode; and
the detection module is configured to detect a second dim light signal emitted from the power pump region when the chip is in the pre-charge working mode.
