Does anyone have an example of how to build a DRAM refresh circuit using discrete TTL logic with perhaps the odd PAL thrown in. I have been looking in handbooks from various memory suppliers and their examples all use DRAM controller chips. I am trying to keep costs down and want to use parts I have on hand. If you ahve anything at all that you can paper mail or FAX send me an E-mail. thanks Graham Heyes
