Intermediate memory system for data transmission - uses fast access buffer memory to reduce mean access time of calculator to auxiliary memory e.g. disk data

摘要

The intermediate memory system comprises a buffer memory associated with two coupling devices and a controlling device. One coupling device, connected to at least one calculator, transmits data as controlled by read or write commands issued by the calculator. The other coupling device, connected to at least one auxiliary memory, stores data en route to or from the calculator. A large capacity fast access electronic buffer memory always contains some of the data stored in the auxiliary memory. The controlling device controls the exchanges between the coupling devices and the buffer memory. This intermediate memory system is used to reduce the mean access time of one or more calculators/computers when accessing one or more auxiliary memories such as disks.
