Kilobyte atomic memory. STM image (96 × 126 nm, I = 2.00 nA,V = +500 mV, T = 1.5 K) of a 1,016-byte atomic memory, written to a passage from Feynman’s lecture ‘There’s plenty of room at the bottom’. The various markers used are explained in the legend below the images. The memory consists of 127 functional blocks and 17 broken blocks, resulting in an over all areal density of 0.778 bits nm−2.
