BJT npn transistor with self-holding

Good morning everyone, I'm making a simple circuit and I was thinking of using a self-holding relay as a rudimentary memory, I would like to ask you if instead of a relay I can use a BJT npn transistor?
Connecting the emitter pin to the base as a self-holding circuit, what resistors should I put?

Thanks

A triac with DC may have the same effect. For something more practical google for latch circuits.

Can you show what you intend to do?

You can make the equibalent of an SCR with TWO transistors as described here

flip-flop

I'll start by saying that I don't really know much about it, but I was thinking something like this, where the emitter would generate a feedback signal to the base

Then set the state to 0 by removing power to the base and collector for an instant, while to set it to 1 give power to the collector and only a pulse to the base, would it work?

Forgive me but I had already heard of a thyristor but I didn't know it was used for this purpose, ultimately I think that, although both the latch and the flip flop and the tristor have a similar function, the one that works for me is the latch.

Thanks to all

That wont work
