Which of the following statements regarding static RAM (SRAM) and dynamic RAM (DRAM) is TRUE?
A.
Static RAM (SRAM) stores information bits as long as power to the memory chips is not interrupted.
B.
Static RAM (SRAM) stores data in IC capacitors while Dynamic RAM (DRAM) stores data IC transistors.
C.
Static RAM (SRAM) is much faster than Dynamic RAM (DRAM) but is more expensive.
D.
Static RAM (SRAM) can store approximately 75% more data than Dynamic RAM (DRAM) of the same size.
Explanation:
Static RAM (SRAM) is much faster than Dynamic RAM (DRAM) but is more expensive than DRAM.Incorrect Answers:
A: Static RAM (SRAM) stores information bits as long as power to the memory chips is not interrupted.
B: Dynamic RAM (DRAM) stores data in IC capacitors that lose their charge over time while Static RAM (SRAM) stores data in IC transistors.
D: Static RAM (SRAM) can store approximately 75% less data than Dynamic RAM (DRAM) of the same size, and is more expensive than DRAM.
