HP 100TB Memristor drives by 2018 – if you're lucky, admits tech titan

HP has warned El Reg not to get its hopes up too high after the tech titan's CTO Martin Fink suggested StoreServ arrays could be packed with 100TB Memristor drives come 2018. In five years, according to Fink, DRAM and NAND scaling will hit a wall, limiting the maximum capacity of the technologies: process shrinks will come to a …

Resistance is futile? Memristor RAM now cheap as chips

Cheaper memristors could result from an accidental discovery at University College London. The HP-popularised memristor device is a form of ReRAM – resistive RAM – and is fairly expensive to make. Metal oxide-based ReRAM technology promises to combine minimum memory speed with NAND non-volatility and be able to provide higher …

HP & Hynix join forces for memristor fab

HP is partnering with Hynix to bring Memristor technology from lab to fab. The Memristor, posited as a fourth basic electrical circuit element, is said by HP to have the potential to be a form of uniform memory that could replace flash (being non-volatile), DRAM and even hard disk drives. It could possibly perform logic …
