Everspin throws first ST-MRAM chips down, launches commercial spin-torque memory era

DNP Everspin

Who says scientific breakthroughs never amount to anything? Everspin has followed up on research developed by IBM, TDK and German researchers years back and released the first commercial spin-torque magnotoresistive RAM (ST-MRAM) onto the market. The technology works by taking advantage of electron "spin" to store data in a magnetic, rather than electronic state, providing non-volatile memory that doesn't wear out. The company said the first chips were about 50 times the cost of flash memory by size, but where a typical NAND module can perform about 800 iOPS, ST-MRAM is capable of 400,000 -- making it ideal for SSD caching and other demanding applications. Everspin has started shipping working samples of the 64MB DIMMS in a DDR3 form factor, saying that future versions will scale to gigabyte capacities and faster speeds -- keeping Moore's Law hurtling inexorably forward. Check the PR after the break for the company's spin on it.

Permanent quartz glass data storage announced by Hitachi, could hit market by 2015

Hitachi announces permanent Glass Storage

Sure, we can store huge quantities of bits in a tiny space, but how long will that data last? Current optical, magnetic and flash storage media have limited shelf lives, so Hitachi has announced a new way of locking up ones and zeros in quartz glass for hundreds of millions of years. The data can be etched with a laser in three layers on the crystals at a density slightly higher than a CD, then read out with an optical microscope, meaning that future generations could restore the info without needing a proprietary drive. The technology could come to market in three years, according to the research lab -- but would likely be targeted at companies first, who would need to send in their data to be encoded. Hitachi said the media withstood two hours of 3500 degree Fahrenheit temperatures in testing without data loss, meaning that archaeologists from the future may one day uncover your questionable taste.
