False-colour scanning electron micrograph (SEM) of part of a 256-kilobyte Dynamic Random Access Memory (DRAM) integrated circuit or silicon chip. DRAMs do not store information on a permanent basis; instead their memory cells are refreshed every 2 milliseconds. A mainframe computer might contain 400-1000 DRAMs. Magnification: x4,000 at 8x10,x500 at 35mm size | |
