Tiny new memory cell
Too small to be seen in detail with an ordinary microscope, this mite of a memory cell developed by Bell Telephone Laboratories appears here courtesy of the scanning electron microscope. (Some of the dust particles in this photo are the size of a wavelength of light.) The cells are a new kind of silicon semiconductor memory called “charge transfer diode memory,” and are destined for future telephone switching systems, where they will permit computer-memory access speeds in billionths rather than millionths of a second.
