The invention provides a misunderstanding prevention resistance random access memory and a production method thereof. The structure of the resistance random access memory lies in that a resistance random medium layer and an Ag electrode membrane layer are sequentially formed on a Pt membrane layer of a Pt / Ti / SiO2 / Si substrate; the resistance random medium layer comprises a first ferrite bismuth membrane layer, a second ferrite bismuth doped silver membrane layer and a third ferrite bismuth membrane layer which are sequentially formed. By the arrangement, stable resistance changes are presented, resistances of high-low resistance states are quite concentrated in distribution, and the high resistance and the low resistance are large in difference, so that confusion of the high and low resistances is less prone to occurrence, and misunderstanding is not easy to occur during data reading. The resistance random access memory is remarkable in switch effect and quite beneficial to readout of the memory. In addition, anti-fatigue performance of the resistance random access memory under the high-low resistance states is quite good.

The invention discloses a circuit board and a manufacturing process of a transparent LED display screen, wherein the circuit board includes a PCB board and LED lamp beads arranged on one side of the PCB board; the PCB board includes a substrate, and the two sides of the substrate are A prepreg and an etched copper-clad board are sequentially arranged; the surface of the PCB board is coated with an insulating and heat-dissipating layer. Different from the conventional insulation layer, heat dissipation layer and waterproof layer, the coating layer is too thick and the combination between the layers is not good, which can not achieve the corresponding effect. Waterproof as a whole, it has the advantages of being lighter and thinner and does not need to consider the bonding problem between multiple layers. It also has better performance in heat dissipation and waterproofing, which can meet the needs of the market.
