Simple adaptation of the DFF using just NOR Gates.
"D" is the Square Wave Source.
"E" is the 5V DC Source.
If E=1, Q follows "D".
If E=0, last state of "D" is stored,
This is possibly the simplest approach to understanding how memory works. Mostly the DFF is done with NAND Gates, however after searching for such a circuit using only NOR Gates returned nothing, I am now submitting this in hopes to fill that gap for the community.

Q = Output
Q' = Second output
D = Data/Signal
E = Enable
DFF = D Flip Flop
