Word Origin and History for computer-memory

memory

n.

mid-13c., "recollection (of someone or something); awareness, consciousness," also "fame, renown, reputation," from Anglo-French memorie (Old French memoire, 11c., "mind, memory, remembrance; memorial, record") and directly from Latin memoria "memory, remembrance, faculty of remembering," noun of quality from memor "mindful, remembering," from PIE root *(s)mer- "to remember" (Sanskrit smarati "remembers," Avestan mimara "mindful;" Greek merimna "care, thought," mermeros "causing anxiety, mischievous, baneful;" Serbo-Croatian mariti "to care for;" Welsh marth "sadness, anxiety;" Old Norse Mimir, name of the giant who guards the Well of Wisdom; Old English gemimor "known," murnan "mourn, remember sorrowfully;" Dutch mijmeren "to ponder"). Meaning "faculty of remembering" is late 14c. in English.

I am grown old and my memory is not as active as it used to be. When I was younger I could remember anything, whether it had happened or not; but my faculties are decaying now and soon I shall be so I cannot remember any but the things that never happened. It is sad to go to pieces like this, but we all have to do it. [Mark Twain, "Autobiography"]
Computer sense, "device which stores information," is from 1946. Related: Memories.

computer-memory in Science
memory
  (měm'ə-rē)   
    1. 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.

    2. The collection of information gained from past learning or experience that is stored in a person's mind.

    3. A piece of information, such as the mental image of an experience, that is stored in the memory.

    4. A part of a computer in which data is stored for later use.

    5. 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.

computer memory

device that is used to store data or programs (sequences of instructions) on a temporary or permanent basis for use in an electronic digital computer. Computers represent information in binary code, written as sequences of 0s and 1s. Each binary digit (or "bit") may be stored by any physical system that can be in either of two stable states, to represent 0 and 1. Such a system is called bistable. This could be an on-off switch, an electrical capacitor that can store or lose a charge, a magnet with its polarity up or down, or a surface that can have a pit or not. Today capacitors and transistors, functioning as tiny electrical switches, are used for temporary storage, and either disks or tape with a magnetic coating, or plastic discs with patterns of pits are used for long-term storage
