'memory-free' originates from the combination of 'memory' and 'free', where 'memory' refers to the ability to store information and 'free' means without or lacking.

'memory' and 'free' have been used separately in English for centuries, but their combination into 'memory-free' is a modern development, reflecting advancements in technology and computing.

Initially, 'memory' referred to the human ability to remember, but in modern usage, it often refers to computer storage. 'Free' has consistently meant 'without' or 'lacking'.
