A neural network without memory can't do that or can't do it as well perhaps?

In fig. 5a, they compare its performance to that of an LSTM trained on the same problem, and it does seem to do much better.

I am guessing for an LSTM based neural network to learn memory sequencing for the purpose of solving problems will need a much deeper and wider network which a separate memory block tries to provide with ready made logic and much simpler network so it doesn't have to learn those actions.
