Simulation of a cobalt silicide/Si hetero-nanocrystal memory
A nanocrystal memory using CoSi2/Si hetero-nanocrystals as floating gate was proposed. Numerical investigations on the writing, erasing and retention were performed. The hetero-structure provides an extra quantum well for the charge to achieve much longer retention time while maintains a writing/erasing speed similar to that of Si nanocrystal memory.
