- Correct Answer
- read/write
- 1. What is the major difference between SRAM and DRAM?
Options- A. DRAMs must be periodically refreshed.
- B. SRAMs can hold data via a static charge, even with power off.
- C. The only difference is the terminal from which the data is removed?from the FET Drain or Source.

- B. capacitor-capacitor drain
- C. charged-capacitor device
- D. charge-coupled device Discuss
- 5. The reason the data outputs of most ROM ICs are tristate outputs is to:
Options- A. allow for three separate data input lines.
- B. allow the bidirectional flow of data between the bus lines and the ROM registers.

- D. 157 Discuss
- 9. A 64-Mbyte SIMM is installed into a system, but when a memory test is executed, the SIMM is detected as a 32-Mbyte device. What is a possible cause?
Options- A. The memory module was not installed properly.
- B. The voltage on the memory module is incorrect.
- C. The most significant address line is stuck high or low.
