A new word in computer technologies is a usage of diamonds for computer memory. It was reported that Johns Hopkins University engineers were working on changing that would allow improving the storage capacity and elongating the period of data storage of the current memory media. The changes are planned to touch an inexpensive GST alloy for phase-change memory. GST consists of antimony, germanium, and tellurium but a new alloy is announced to be 100 times faster than the current. The study’s lead author and a doctoral student at the Whiting School of Engineering at Johns Hopkins University Ming Xu stated that a phase-change memory with a new alloy could be 100,000 times more rewritten, and they were planning to replace the computer hard drives within five years.
