diode latch

[wiresaho]

Is it possible to make a latch with diodes   -  I saw this ->

Or is it including transistors with it to get the memory bits?

You can make gates out of just diodes, but there is no amplification, no small current able to drive larger current.
So I believe they still use transistors as buffers/inverters. Otherwise you can't series diode-based gates together without absurd current requirements from each additional gate adding more draw through the gates before it.

Here is the datasheet of the hex NOR board:

and here is the schematic of a NOR gate from the datasheet:



Read the datasheet for a detailed desciption of how it works. Note that V_RF is an AC source operating in the MHz range.

If it didn't have inductors in it,  it would probably work hydraulicly and pneumaticly as well.

But they do have pneumatic "transistors" as well.

lolll   wow    but consumes almost 5  amps  ...  current hungry for sure

Negative resistance devices can be used in place of amplification, like tunnel diodes, DIACs, or 4 layer diodes.  Neon bulbs can also be used.

Interesting.
