    Also the contact resistance can be customized based on electronics need where contact pills can be of different resistance. A general carbon pill can be of around 20 to 100 ohms, a low resistance contact pill can be up to 10 ohms. Gold or Supra-Conductive pills can be used to obtain a resistivity as low as 1 ohm.

    304, 304H, and 304L all possess the same nominal chromium and nickel content and also possess the same corrosion resistance, ease of fabrication, and weldability. The difference between 304, 304H, and 304L is the carbon content, which is < 0.08, < 0.1, and < 0.035% respectively (also see UNS designations S30400, S30409, & S30403 respectively ...

  8. Resistive random-access memory - Wikipedia

    en.wikipedia.org/wiki/Resistive_random-access_memory

    Resistive random-access memory (ReRAM or RRAM) is a type of non-volatile (NV) random-access (RAM) computer memory that works by changing the resistance across a dielectric solid-state material, often referred to as a memristor. One major advantage of ReRAM over other NVRAM technologies is the ability to scale below 10 nm.
