Some scholars have argued that because most of Ibn Battuta's account of the places his visited are from memory they are not reliable?

The answer is True.

Explanation:

Scholars actually believe most of Ibn Battuta's account of his travels is reliable; however, his alleged journey to Bulgary was proved to be invented. Some other discrepancies, lapses and uncertainties in the arrangement of his travels are due more to lapses in his memory than to intentional fabrication.
