    First is a technical question:
    What type of RAM is used for digital camera buffers?

    Now the logistic question:
    Is the price of this RAM so much per meg that even the cheapest
    cameras can't have enough memory for, say, a 10-shot buffer? Last I
    checked, individual chips of Hyundai / Hynix / Samsung / Micron etc
    DDR are very inexpensive in large quantities -- pennies per chip if I
    recall. Now, granted, cameras don't use the large DDR chips that our
    PC RAM modules use, but they must be of similar design , function and
    cost, no?
    I'm sure there are issues I haven't considered, which is why I've
    brought this up. I'm just curious to know.

    Any insights?

  2. Several factors to consider. Price, but also, size, speed (may depend
    on price) and very important, power requirements. Memory can be energy
    hogs.
