It's more about rejecting primarily photographic memory - is that very PC? (5)
I believe the answer is:
eprom
'memory is that very pc?' is the definition.
'eprom' can be an answer for 'memory' (I've seen this before). I am not certain of the rest of the definition.
'it's more about rejecting primarily photographic' is the wordplay.
I cannot quite understand how this works, but
'more' could be 'm' and 'm' is found in the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is present in the answer.
The remaining letters 'pro' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for eprom that I've seen before include "Memory" , "chip" .)
