idetic memory vs photographic memory.
I heard 'photographic memory' is not correct. So, how do you call this kind of spelling?

You're still using "grammatical" wrongly. Grammar only relates to sentence structure above the word level.
A misspelling or improper use of a word is not a grammar error.
You're referring to a semantic error, or a vocabulary error, or an error in usage of a word.
