EPROM erase times and lifespan

Yes, but I would have thought that smaller devices had less charge to discharge (if you see what I mean). Assuming the voltage on the floating gate is much the same in both cases (and if anything it'd be smaller on later/higher capacity devices), the charge is going to be roughly proportional to the area of the floating gate (since the capacitance between that gate and whatever you reference it to is proportional to that area). I believe that if you have a number of charged bodies in a mediaum of resistivity rho and permitivity epsilon (as normal), the time constant of that system (to equalise the charges) is independnat of the shapes and positions of the charged bodies, it is simply rho * epsilion. th return ot the 'intellegent' EPROM ereaser, my worried is that do we _know_ that the rest of the chip (addresss decoder, sense amplifiers, etc) will work correcting when irradiated with short-wavelength UV? In other words is the readout of the chip even meaningful under such conditions? -tony
