An amplifier doesn't look at voltage and "freshens it up", in an SRAM cell, the amplifier is running in clipping and unlike a DRAM cell requires no clocking, only supply voltage. A pair of transistors does not behave like that since they operate over current. You need two inverting amplifier, which is more complex and isn't simply "looking at voltage to freshen in up".
If my attempt to make everything more digestible failed in your opinion, then I guess that is it, it's your opinion on the matter.
- Dylan16807 8y ago> An amplifier doesn't look at voltage and "freshens it up" Sure it does, as long as you set the proper bias and use a definition of "fresh" that makes sense for digital signals. > unlike a DRAM cell requires no clocking Yes, that's why it's 'continuous'. > You need two inverting amplifier You don't need to use that design. It just happens to have reasonable size and leakage characteristics. > more complex and isn't simply "looking at voltage to freshen in up" That circuit is a hundred times simpler than the DRAM refreshing circuit you used those words to describe!
- zaarn 8y agoI described no DRAM refreshing circuit, I describe a SRAM cell, I don't believe that definition of fresh is suitable for the discussion nor is it fitting when talking about SRAM, I also never said it wasn't continuous, ie linear, I did disagree with the wording that made it sound like there is a refresh process that happens repeatedly.
- Dylan16807 8y agoOh. I thought "The process is entirely analog, ie, there is no refresh circuit that looks at the voltage and says "that's almost a ON, better fresh up the voltage"." was talking about DRAM as a comparison. Sorry about that. > I did disagree with the wording that made it sound like there is a refresh process that happens repeatedly. Repeatedly continuous...? Nevermind though.
