An even more interesting exercise would be to implement a DDR5 driver circuit for the 1 bit of RAM. Typical DDR5 interfaces take hundreds to thousands lines of Verilot/VHDL so quite a few transistors will be needed.

You need at least two words of data to have a meaningful DDR...

That's how DRAMs work today

And that's why DRAM is so much denser than SRAM. DRAM takes [about] 1 transistor per bit; SRAM takes roughly 8.

4 or 6 transistors is more common:

If you are a software person looking to learn a few more things about electronics I recommend the videos of Ben Eater on you tube. Here is one that he explains the SR latch: https://www.youtube.com/watch?v=KM0DdEaY5sY Also the lectures by this amazing MIT professor: https://www.youtube.com/watch?v=AfQxyVuLeCs

Also https://www.nand2tetris.org/ and "Digital Design and Computer Architecture" by Harris and Harris go into building a computer from the ground up.

It's great to add relevant information, but in the future, could you please do it in a way that greets and expands on what you're replying to, rather than one-upping or putting it down? The two styles of responding have opposite effects on discussion: one opens it up for further exploration, while the second constricts it or closes it. In improv, that is called "blocking": https://improwiki.com/en/wiki/improv/blockin…

Please see my response to other comment and stop chasing me. Jesus Dang, it feels like you have something personal with me lately. If you want a date, just ask for it instead.

It isn't personal. I don't remember your username. There are too many to remember them all; it looks like I've posted hundreds of comments since the last time I replied to you.
