Rice's Silicon Memristor Aims to Beat HP

HP announced it had begun licensing its titanium-oxide based memristor to memory-chip makers, Hynix being the first, but now Rice University is offering a competing license using a simpler silicon-oxide formulation. Look for HP to compete with researchers worldwide on competing memristor materials, including Samsung, Elpida and Micron Technology working on ReRAM at IMEC over the next three years.

Here is what EETimes says about memristors: Memristors made from pure silicon could enable resistive random access memory (ReRAM) that are simpler and cheaper to manufacture than Hewlett-Packard Co.'s titanium-based formulation, according to researchers at Rice University. In collaboration with fabless chip design house PrivaTran Inc. the team demonstrated a proof-of-concept ReRAM that packs only 1-kbit, but which they claim can be scaled beyond the densities of flash...
