The First 294,912-Bit (288K) Dynamic RAM

Like a work of art, this chip has a design all its own. It is made up of four 72K memory grids (the circuits with the crisscrossed features between gold-colored columns). The irregular elements in the center are amplifiers; the dark balls are lead-tin connectors for wires linking the chip to the outside world. The gold-colored columns contain decoding and amplifying circuits. A bit may be read out of or written into this IC in 450 billionths of a second, only half the speed of other RAMs. The photo's colors were created by bright lights shone onto the chip. Actual size: 0.149 inches x 0.259 inches.
