Which type of RAM is faster and DOES NOT require refreshing?
-
A.
ROM
-
B.
Flash Memory
-
C.
DRAM
-
D.
SRAM
Correct Answer:
D. SRAM
Explanation:
SRAM, or Static Random Access Memory, is the correct answer because it is faster than DRAM and does not require periodic refreshing to maintain data integrity. Unlike Dynamic RAM (DRAM), which uses capacitors that leak charge and must be recharged every few milliseconds, SRAM utilizes a flip-flop circuit made of multiple transistors to store each bit. As long as continuous power is supplied, SRAM will retain its data without the need for refresh cycles. Because it avoids these cycles and has a more direct architecture, SRAM provides significantly lower latency and higher speeds, making it the preferred choice for a processor's cache memory.
