The memory unit is not understood.

Dear Yanzu, this is the logic diagram provided by the design institute. What does it mean and what role does it play? What do the SO R and S RO in the box stand for?
A logic diagram is a graphical tool that represents circuit logic functions and signal transmission relationships. It describes the connections and signal flow directions between various logic units, helping us understand and design circuits. In the logic diagram you provided, the SOR in the box represents "Set-Reset", and the SRO represents "Set-Reset Output". This is a commonly used logic gate circuit used to store a binary value. When the SOR input signal is triggered, the output signal will change according to the input signal. For example, when the input signal is S=1 and R=0, the output is 1 ； When the input signal is S=0 and R=1, the output is 0 ； When the input signal is S=0, R=0, the output remains unchanged or cannot be determined. Other parts in the logic diagram may represent other logic gates or functional modules, and the specific meaning needs to be understood in conjunction with the entire circuit. Hope this helps answer your question. .
The explanation is really good. I can understand it all. There is one thing you missed in your explanation, that is, SOR means set output reset output. What does the second pin output mean? I don’t understand Z1.

SO means S is set first: When R and S are both 1, S takes priority, Z=1, Z1=0. Pay attention to the truth table on the right. When R=1 and S=1, Z=1 RO is R reset priority.: When R and S are both 1, R takes priority, Z=0, Z1=1. Pay attention to the truth table on the right side. When R=1 and S=1, Z=0. The right side of X, Y, Z, Z1, 0, 1 is the truth table, indicating the values of Z and Z1 when X and Y are 0 and 1 respectively. In particular, when X=0 and Y=0 in the table, Z=X and Z1=X means that the original values of Z and Z1 remain unchanged.
The one above, 0 is in S, Z is in accordance with X, Z is whatever X is, Z1 is opposite to Z； The 0 below is in R, Z1 listens to Y, Z1 is what Y is, and Z is the opposite of Z1
