Which of the following statements describe the difference between static RAM (SRAM) and dynamic RAM (DRAM)? (Choose all that apply)
A.
Static RAM (SRAM) stores data in IC transistors to store data, and is capable of maintaining the data for as long as power to the memory chip is not interrupted. Dynamic RAM (DRAM) stores data in IC capacitors that lose their charge over time, and require periodic data-refreshing operations.
B.
Dynamic RAM (DRAM) stores data in IC transistors to store data, and is capable of maintaining the data for as long as power to the memory chip is not interrupted. Static RAM (SRAM) stores data in IC capacitors that lose their charge over time, and require periodic data-refreshing operations.
C.
Dynamic RAM (SRAM) is much faster than Static RAM (SRAM) but can store approximately 25% more data than Static RAM (SRAM) and is more expensive than Static RAM (SRAM).
D.
Static RAM (SRAM) is much faster than Dynamic RAM (DRAM) but can store approximately 75% less data than Dynamic RAM (DRAM) and is more expensive than Dynamic RAM (DRAM).
Explanation:
Static RAM (SRAM) stores data in IC transistors to store data, and is capable of maintaining the data for as long as power to the memory chip is not interrupted. Dynamic RAM (DRAM) stores data in IC capacitors that lose their charge over time, and require periodic data-refreshing operations. Static RAM (SRAM) can store approximately 75% less data than Dynamic RAM (DRAM) of the same size, and is more expensive than DRAM.Incorrect
Answers:
B: Static RAM (SRAM) stores data in IC transistors to store data, and is capable of maintaining the data for as long as power to the memory chip is not interrupted. Dynamic RAM (DRAM) stores data in IC capacitors that lose their charge over time, and require periodic data-refreshing operations..
C: Static RAM (SRAM) can store approximately 75% less data than Dynamic RAM (DRAM) of the same size, and is more expensive than DRAM..
