Computer memory made from sugar cube

Published in Chemistry World, 19 Mar 2014

A sugar cube that functions as computer memory has been created by scientists in the US. The sugar-based metal–organic framework infused with rubidium hydroxide can be switched between high and low resistance states, in a similar way to resistive random-access memory (RRAM).

Metal–organic frameworks (MOFs) are made from organic molecules held in a 3D lattice by metal ions or clusters. Typically porous, they are widely investigated for storing gases, such as hydrogen for fuel. But Bartosz Grzybowski and colleagues at Northwestern University in Evanston, Illinois, have been investigating MOFs for storing something entirely different: information. […]
