'memory-focused' originates from the combination of 'memory' and 'focused', where 'memory' refers to the faculty by which the mind stores and remembers information, and 'focused' means concentrated on a particular point or task.

'memory' comes from the Latin word 'memoria', and 'focused' is derived from the Latin 'focus', meaning 'hearth' or 'fireplace', which evolved to mean 'center of activity or interest'.

Initially, 'focus' meant 'hearth', but over time it evolved into its current meaning of 'center of interest or activity'.
