I don't know how compact it is compared to others and it's almost certainly slower than just about anything else out there, due to the MASSIVE amount of torches; however, I'm just happy that it works xD

It's designed to be extendable to any size required, with the sky serving as the only limit, but I think bank switching could be implemented if you DO actualy run into the sky.

I owe SkyshockX most of the credit for his awesome DFF design.

I'm not sure if I made the schematic correctly, but if anyone wants it, it's over here.

That is definitely one of the best RAM builds I've seen. How many bits is it?(do nibbles=bits?)

Really? Thanks! :biggrin.gif:

Oh, and nibbles = half-bytes.

So there's 64 bits total, but again: I designed it to be relatively easy to expand. So making it into 16 bytes would just be a matter of adding more registers away from the demultiplexer. Expanding the address space would only require increasing the demultiplexer's size.

I REALLY like the way you solved the address decode problem in a nice, compact way.

That is very clever!

Thanks! I hate how slow it is, though, but I guess that's the the price I have to pay for compactness.

Actually, now that I think about it, decoding the address wasn't the biggest problem for me. Selecting a specific register and outputting its stored value was a much bigger challenge. Maybe I'm missing something, but I can't think of a way to do it that doesn't involve the use of a crapload of pistons. I must be missing something.

I just posted a couple of wiring tips that might help to simplify the output section.

Hope this helps.

Derp. Now I feel stupid for not thinking of this :tongue.gif: Thanks!

Pistons can be very problematic in bulk .....

Which is why I had to use a bunch of repeaters, but I fixed that problem in the updated design in the post right before yours.

Doesn't the torch tower add a huge delay? Anyway, love the design. So nice and compact! :smile.gif:

Yes. Huge. You have enough time to walk around and watch the torches change when you switch the address, or hit the clock :tongue.gif:

Just updated the OP with a new screenshot and schematic :biggrin.gif:

holy ****! it looks epic!!
what does it do XD sorry im stupid when it comes to advanced red stone circuitry

Quote from Spikeyroxas

what does it do?

RAM (Random access memory) allows you to select a specific address and write whatever is at the data inputs to it when the clock is activated. This specific design has 16 addresses, each 4 bits in length, meaning you can store up to 64 bits worth of data! (I know, I know... Freakin' AWESOME, right?! :tongue.gif:)

Bank switching! (Holy crap, my head hurts >_<)


I've made no attempt to compact it yet...

Quote from SkyshockX

I was thinking that with your original design you could have the address lines / decoders between two memory banks and just add one more line for select.

:blink.gif: Really like this idea. I'll try it when I get the chance. Thanks!
