- Question
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.
- D. Dynamic RAMs are always active; static RAMs must reset between data read/write cycles.
- Correct Answer
- DRAMs must be periodically refreshed.
- 1. Why do most dynamic RAMs use a multiplexed address bus?
Options- A. It is the only way to do it.
- B. to make it faster
- C. to keep the number of pins on the chip to a minimum Discuss
- 2. The mask ROM is ________.
Options- A. permanently programmed during the manufacturing process
- B. volatile
- C. easy to reprogram
- D. extremely expensive Discuss
- 3. CCD stands for ________.
Options- A. capacitor charging device
- B. capacitor-capacitor drain
- C. charged-capacitor device
- D. charge-coupled device Discuss
- 4. 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.
- C. permit the connection of many ROM chips to a common data bus.
- D. isolate the registers from the data bus during read operations. Discuss
- 5. Suppose that a certain semiconductor memory chip has a capacity of 8K × 8. How many bytes could be stored in this device?

Options- A. mounds
- B. lands
- C. holes
- D. pits Discuss
- 8. The location of a unit of data in a memory array is called its ________.
Options- A. storage
- B. RAM
- C. address
- D. data Discuss
- 9. For the given circuit, what memory location is being addressed?
Options- A. 10111
- B. 249
- C. 5
- D. 157 Discuss
- 10. 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.
- D. The address decoder on the SIMM is faulty. Discuss
