Who invented the "cache"?

  1. Question for the old-timers:

    Who came up with the concept of "cache" or "cached memory"? When? And
    what is the first written reference to it?

    I suspect it appeared in the 70's, but it could be older than this.

    (Am I in the right newsgroup?)

    It was almost certainly IBM- and disclosed in the IBM Journal.
  3. One of the first computers, the Manchester University machine, circa 1951,
    used a CRT screen (very unreliable electrostatic storage), to hold blocks
    recently read from the drum.
    This is pretty much a cache.
  4. come on you reds!

    Right! The invention of cache can then be attributed to the first
    Ugha-Ugha cave man who discovered it was easier to store water in his
    cave than make a trip to the river each time.
  6. As old as that! But who came with the name? I guess I may have to check
    with IBM, as Fred Bloggs suggests.
  7. In that case, it was probably a woman.

    The word itself goes way back to cacher, french, to press, hide. So
    it's no different than calling a CCD a bucket-brigade delay. Just a
    new use for an old word.

    This one took me by surprise...

    Cored rope for memory?
  12. But it could have been named anything else. Who decided to call it
    "cache" instead of FTM (Fast Temporary Memory), for example?
  13. So who was responsible for flushing the cache?

    Sqirrels invented the cache.
