This IBM computer memory chip, 3/8-inch long, stored more than one million bits of information. IBM was the first to develop and mass-produce chips of this density. At the beginning of 1987, the only such chips operating in the industry were in the IBM 3090, System/38 and System/36 computers and in the IBM 3880 disk "cache" control unit. (VV3131)
