memory       (měm'ə-rē)  Pronunciation Key  The ability to remember past experiences or learned information, involving advanced mental processes such as learning, retention, recall, and recognition and resulting from chemical changes between neurons in several different areas of the brain, including the hippocampus. Immediate memory lasts for just a few seconds. Short-term memory stores information that has been minimally processed and is available only for a few minutes, as in remembering a phone number just long enough to use it. Short-term memory is transferred into long-term memory, which can last for many years, only when repeated use of the information facilitates neurochemical changes that allow it to be retained. The loss of memory because of disease or injury is called amnesia. The collection of information gained from past learning or experience that is stored in a person's mind. A piece of information, such as the mental image of an experience, that is stored in the memory. A part of a computer in which data is stored for later use. The capacity of a computer, chips, and storage devices to preserve data and programs for retrieval. Memory is measured in bytes. See more at hard disk, RAM, ROM.

Memory

Mem"o*ry\, n.; pl. Memories. [OE. memorie, OF. memoire, memorie, F. m['e]moire, L. memoria, fr. memor mindful; cf. mora delay. Cf. Demur, Martyr, Memoir, Remember.]

1. The faculty of the mind by which it retains the knowledge of previous thoughts, impressions, or events.

Memory is the purveyor of reason. --Rambler.

2. The reach and positiveness with which a person can remember; the strength and trustworthiness of one's power to reach and represent or to recall the past; as, his memory was never wrong.

3. The actual and distinct retention and recognition of past ideas in the mind; remembrance; as, in memory of youth; memories of foreign lands.

4. The time within which past events can be or are remembered; as, within the memory of man.

And what, before thy memory, was done From the begining. --Milton.

5. Something, or an aggregate of things, remembered; hence, character, conduct, etc., as preserved in remembrance, history, or tradition; posthumous fame; as, the war became only a memory.

Syn: Memory, Remembrance, Recollection, Reminiscence.

Usage: Memory is the generic term, denoting the power by which we reproduce past impressions. Remembrance is an exercise of that power when things occur spontaneously to our thoughts. In recollection we make a distinct effort to collect again, or call back, what we know has been formerly in the mind. Reminiscence is intermediate between remembrance and recollection, being a conscious process of recalling past occurrences, but without that full and varied reference to particular things which characterizes recollection. "When an idea again recurs without the operation of the like object on the external sensory, it is remembrance; if it be sought after by the mind, and with pain and endeavor found, and brought again into view, it is recollection." --Locke.

To draw to memory, to put on record; to record. [Obs.] --Chaucer. Gower.
