Abstract The mask ROM includes one substrate layer, one first doped layer, one second doped layer and one encoding layer. The first doped layer formed on the substrate is used as the reserved ground line of the mask ROM, the second doped layer formed on the first doped layer is used to form one switch together with the first doped layer, and the encoding layer formed on the first doped layer and the second doped layer has its data read depending on the switch during operation.
