Abstract
An information processing system includes a first memory, a second memory such as a printer buffer capable of a high speed access and independent of the first memory, and an external storage device such as a fixed or hard disk. A first processor primarily uses the first memory as a storage area of information. A second processor primarily uses the second memory as a storage area of information. The second memory and the external storage are selectively used by the first processor auxiliary storage according to the usage status of the first memory and the usage status of the second memory. The second memory is used first as auxiliary storage because of its faster access speeds, and only if the second memory is currently unavailable, is the slower access speed, external storage device used.
