RAM 4 numbers of 4 Bit with a D Flip flops and adress decoder 2bit, you can WRITE 4 numbers of 4bit and READ them (L.I.F.O)
# Write: make the first pin in 1 value and input the 1st number with the 4 inputs and press the swich bouton to store the next (wait a few secondes to press the swith because the simulation it's very slow).
#Read : change the value of the first pin to 0 and press the siwtch bouton to go to the next number.
