Logic Chip, Heal Thyself


If a single fault can kill a logic chip, that doesn’t bode well for longevity of complex multi-chip systems. Obsolescence in chips is not just an industry ploy to sell more chips. It is a fact of physics that chips don’t last more than a few years, especially if overheated, and hit with higher voltage than it can stand. The testing industry does a great job finding defects during manufac... » read more

Power/Performance Bits: Jan. 21


Two-layer MRAM Scientists at Tokyo Institute of Technology propose a simpler MRAM construction that could perform faster with less power than conventional memories. The idea relies on unidirectional spin Hall magnetoresistance (USMR), a spin-related phenomenon that could be used to develop MRAM cells with an extremely simple structure. The spin Hall effect leads to the accumulation of elect... » read more
