Memory is a function of the brain: the ability to retain information. Memory is much studied by cognitive psychology and neuroscience. There are multiple types of classifications for memory based on duration, nature and retrieval of perceived items. The terms "storage" and "memory" may also refer to the parts of a digital computer that retain physical state (data) for some interval of time, possibly even after electrical power to the computer is turned off. Where both terms are in use, "memory" is generally used for the faster forms, and "storage" for the slower forms.
Memory is a man's real possession...In nothing else is he rich, in nothing else is he poor.
