Memory module and method of manufacturing the memory module

A memory module, comprising:

• a substrate being at least partially transparent, possessing electrical insulation and comprising electrical circuit, a V-shape notch provided at an upper rim of the substrate, golden finger provided at a lower rim of the substrate and connected to the electrical circuit for inserting into a slot of an external device;
• a mask film being opaque, provided on the substrate and close to the upper rim, having a notch and at least one hollow mark, the notch of the mask film corresponding to the V-shape notch of the substrate;
• at least one memory provided on the substrate, configured close to the golden fingers, and connected to the electrical circuit;
• and
• at least one light emitting diode provided on the substrate and connected to the electrical circuit, each light emitting diode configured at the corresponding hole of the mask film,
• wherein the least one LED is configured to generate and emit light by receiving power from the external device through the golden fingers, or alternatively, by receiving power from an electronic element connected to the electrical circuit on the substrate such that the light from the least one LED is incident onto the hollow mark of the at least one mask film.
