Hi. I think that a few days ago (on a PIC related topic, hence the PIC tag on this post...), someone talked about the lack of static RAM with serial interface. Today I got a mail with a link to this page : http://ramtron.com.12hs.com/S1/18VSIT/9DKZ22QA/M/ Don't know if they "fit the bill"... I noticed that since some time ago, Ramtron says "Unlimited Read/Write Cycles" about their new models. I think that there was *some* limit before, even if very high. /Jan-Erik. -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
