re what to do with old k simms rubin cis ohio state edu daniel j rubin writes how hard would it be to somehow interface them to some of the popular motorola microcontrollers not hard you can do the refreshing and access cycles by software but this hogs most of the available cpu cycles on a low end controller i ve seen some application note from philips that used one of their derivatives as a printer buffer with up to mb of dynamic ram that was accessed and refreshed with software bit banging another alternative would be to use one of those nice dram controller chips that create static ram appearance and all that but they may be too expensive to make it worthwhile segmented memory helps structure software
