Modern day RAM, static or dynamic?

Ok my curiosity is piqued, why in the hell would a pool/spa supply house carry a EPROM extractor tool? They pull a lot of em out of the bottom of pools? :)

At a guess, software updates. If they supply the controller software on an EPROM it's another way to make a little money.

Yeah that makes more sense then the idea I had that they recorded porn on it so they could display at bottom of pool? :)

That's either gonna be seriously low res pr0n, or a bad case of premature ejaculation! :omg:

I never said it was a good idea. :)

Back in the days I knew about hardware there were two types of RAM, the cool static RAM which does exactly what RAM should, and the far more common dynamic which needed refreshing. If I remember correctly, each bit was a tiny capacitor which would slowly leak charge so periodically you'd have to recharge it. The bits were arranged in a grid of rows and columns and there was some concept of RAS and CAS (Row/Column address select) but can't remember the details. That was nearly 30 years ago now I think about it. So, can anyone tell me how it's done these days? I suspect dynamic RAM is a thing of the past. And who can remember wiping the non-volatile memory of the day with UV light? I feel quite nostalgic.

Who cares? Not that I'm a electronics engineer hell bent on inventing the next great RAM device ... Whatever works right now. Incidently, you might look at things like this. Photoshop 64-bit will run on 64-bit OS using 64-bit enabled memory addressing. And the user knows this because he can literally watch all of his RAM being used by whatever process apes the allocation grapher in Task Manager. That's all he cares about. But! The next thing he notices is that his graph goes to "all used up" and his Photoshop tool use starts to lag. he then says to himself "I need more RAM". Then goes out and buys another computer with more RAM. Gets home and installs Photoshop on his new box and notices that he has more power because he just sprung for more RAM! Simple as that. Who cares?
