It is recently shown that when a drop of Glenlivet whisky evaporates, it leaves behind a uniform deposit [Phys. Rev. Lett. 116, 124501 (2016)]. This fascinating finding is utilized in the fabrication of electrochemical metallization memory (ECM) cells. The top (Ag) and bottom (Co) electrodes in the proposed structure are separated by a layer of Glenlivet whisky deposit (an insulator). Measurements show the device response is typical of ECM cells that involve threshold‐type switching, pinched hysteresis loops, and a large difference between the high‐ and low‐resistance states. The surface coating process used in these experiments simplifies the device fabrication and results in a biodegradable insulating layer, which may facilitate the recovery of recyclable materials at the end of the device's use.
