I believe the answer is:

read-only

I'm a little stuck... Click here to teach me more about this clue!

'describing some memories a lecturer entering bank?' is the definition.
I can't judge whether this defines the answer.

'a lecturer entering bank?' is the wordplay.
'lecturer' becomes 'don' (don can mean an academic).
'entering' indicates putting letters inside.
'bank?' becomes 'rely' (to bank on something is to rely on it).
'a'+'don'='adon'
'adon' going inside 'rely' is 'READ-ONLY'.

Can you help me to learn more?

(Another definition for read-only that I've seen is " Like some computer memories".)
