Design and Performance of a CCD Memory System.
Abstract
Three charge-coupled devices, the Fairchild 9216, the Fairchild LARAM, and the Bell Northern CC8M01 are analyzed to determine their suitability as compenents in a memory system. After comparing access time, configuration flexibility, and power consumption, the LARAM is chosen as the primary storage component for the mass memory unit. A memory system whose primary purpose is to test the operation of the CCD's is designed. The system has a capacity of up to ten LARAM devices. Various refresh interval periods and two operating frequencies, 5 MHz for refresh and 1.25 MHz for read/write operations are provided. Operational control of the system is provided through the console of the Hewlett Packard 9820A programmable calculator. To facilitate testing, the calculator provides a record of all address locations and data words used.
