Abstract

Certain types of memories, such as charge-coupled devices (CCDs) and bubbles, can circulate data past a read/write station at a relatively high rate and, therefore, have a relatively high data transfer rate to the control unit, channel, and system. These memories must circulate data to be operative, but this can occur at a much lower rate than the data rate. The analogy in a disk file would be to be able to instantaneously increase or decrease the RPM of the disk and, hence, instantaneously change the data rate.
