Are our brains simply forced to reference information after lapses?About 50 years ago one of my teachers said it wasn't necessary to remember everything. We need to know which book to refer to and refresh our memory when needed. I can't remember which teacher it was but I do remember he said that!
If you can remember the basics such as DC paths, biasing, and signal paths you can look at a circuit and have some idea how it would work. Being able to name the circuits may be a good thing but not necessary. 45 years ago when I taught troubleshooting I told the kids to measure the plate voltage and go from there. If the plate voltage is correct the bias and DC currents are good. If you can't drive a signal through an amp with proper bias look at the AC signal path.
If you are like me you can read and understand the theory today but in a month or two not be able to explain the circuit. Build the circuit and make it work and you can remember the circuit a year later.
