memory

Abstract Noun: "Memory" is an abstract noun because it refers to the mental capacity for retaining and recalling information, experiences, or sensations — or to the actual content remembered. It’s intangible, rooted in the mind rather than a physical object.

It is uncountable when referring to the faculty or capacity: “Memory tends to decline with age.” It is countable when referring to specific recollections: “He shared his memories of childhood summers.”

From Latin memoria (“remembrance, faculty of remembering”), from memor (“mindful”).

• The faculty by which the mind stores and remembers information.

• (Computing) The part of a computer in which data or program instructions can be stored.
