Toshiba plans chippery with mere 0.5V power slurp by 2017

Toshiba is getting ready to announce a low-power semiconductor technology it says will hit the market in scale in 2017. Lower power is something of a holy grail in the world of chips: it means less heat to dissipate away from transistors. That in turn lets devices be clocked at higher speeds (because higher clock speeds increase …
