If the question is: "is there any way to build EPROMs on a conventional N/CMOS process?", the answer is no. You *don't* do EPROMs unless you have access to an EPROM process. (You'd know if you did; the design rules would include constructs for defining the very thin oxide layer that allows you to inject charge onto the bit-cell gate) If you *do* have the process and are simply having problems with circuit design or with making your "Mead-Conway" toolset behave, drop me a line. -- Jay Lessert - Tektronix Inc., Logic Design Systems Division uucp: {ucbvax,decvax,pur-ee,cbosg,ihnss}!tektronix!teklds!jayl CSnet: jayl@tek ARPAnet:jayl.tek@rand-relay
