Computer chip. Coloured scanning electron micrograph (SEM) of metal interconnects on a computer memory chip. Interconnects are patterns that serve as electrical connections between components on an integrated circuit. This is a 64-kilobyte DRAM (Dynamic Random Access Memory) chip. DRAM stores information with capacitors, which must be energized hundreds of times per second to maintain their charge. Without power, DRAM loses its data, so it is said to be volatile memory. Magnification unknown.
