but: If I am not mistaken, that one cant read and write at the same time, because on writing, "ghost" outputs may appear, unless you keep powering the OutputEnable line, in which case it would take 2 ticks to read.
I have seen similar to mine, but never the same (unless I missed something), all either used the comparator to make it smaller by the signal strength shenanagins, or to be able to put the output on a common stack without them interfereing, and not to compensate for the loss in signal strength on the OutputDisable line.
Also, if that is 1 tick write, then mine is 1 tick read and write (plus mine does not invert). But I'm confused at this point, in my testing, I needed a 2 tick long pulse to write, as a 1 tick wont unpower the side comparator, am I misunderstanding something here?
edit: okayy, the side comparator needs 2 tick pulse, the one that actually stores the info only needs 1 tick. That can be done, but that may include some extra latency controller side.
Do you have discord? Also the observer based memory uses no comparators so... Unpowering the rails for 1 tick causes the observer to pulse if no data was written, unpowering the rail (not counting decoder output repeater) is instant so what your left with is a 1 tick "one way" inverter.
You never will read/write to the same cell at the same time so that problem doesn't exist.
Needing to invert inputs or outputs is not an issue, its actually preferred cause then you can take advantage of that in the memory cells and not need to make the first inverter on the AND gate for the read. - Taking advantages of inversions is fun af
I have Discord
When I said ghost output on that, I forgot Observers observe any change, and not just powering up, derp.
That AND gate is for the Demultiplexer at the end, right?
