My textbook has a brief explanation of how semiconductors are used in modern computer chips because they can be made to conduct (by applying enough voltage to excite electrons across the band gap) or to insulate (by dropping the voltage to a lower level or shutting it off entirely) and this conditional, binary state can be used as an 'on/off' logic gate.In modern computer systems, which state is on and which is off? In other words, is it the case that when we increase the voltage to cause conductance in the semiconductor that we have a 1 value and that when we drop the voltage down, we have a 0 value, or is it the other way around?Or is it more appropriate to say read vs write?Does the on/off or read/write state vary from one manufacturer to another? Or from one type of memory to another? I.e. does DDR SDRAM use conducting as on and insulating as off while other forms do it the other way around?P.S. If comp sci isn't the right SE, please could you advise a better SE for this question?
On a semiconductor chip, what state (on/off or read/write) corresponds to conducting or insulating behavior?
