Memory and Storage
21. FIFO is formed by an arrangement of ________.
- diodes
- transistors
- MOS cells
- shift registers
22. Why do most dynamic RAMs use a multiplexed address bus?
- It is the only way to do it.
- to make it faster
- to keep the number of pins on the chip to a minimum
23. CCD stands for ________.
- capacitor charging device
- capacitor-capacitor drain
- charged-capacitor device
- charge-coupled device
24. What is the major difference between SRAM and DRAM?
- DRAMs must be periodically refreshed.
- SRAMs can hold data via a static charge, even with power off.
- The only difference is the terminal from which the data is removed—from the FET Drain or Source.
- Dynamic RAMs are always active; static RAMs must reset between data read/write cycles.
25. Which of the following best describes volatile memory?

- nonmagnetic
26. What is a major disadvantage of RAM?
- Its access speed is too slow.
- Its matrix size is too big.
- It is volatile.
- High power consumption
27. What two functions does a DRAM controller perform?
- address multiplexing and data selection
- address multiplexing and the refresh operation
- data selection and the refresh operation
- data selection and CPU accessing
28. Dynamic memory cells store a data bit in a ________.
