Toshiba has developed what it believes will be a key component of Flash chips capable of storing 100Gb of data. Unfortunately, you"re going to have to wait four more generations of Flash technology to get it. By then, Flash chips will be made using a 10nm process, Toshiba reckons. Today"s Flash chips are made at 65nm or greater. The next step is around 50nm, then 45nm and 32nm. By the time Flash makers reach the last of these, current "floating gate" Flash designs are expected to become impractical.
