Which type of RAM is faster and DOES NOT require refreshing?
Question

Which type of RAM is faster and DOES NOT require refreshing?

A.

SRAM

B.

Flash Memory

C.

ROM

D.

DRAM

Correct option is A

The correct answer is (a) SRAM

Explanation: (Information about the correct answer):
• SRAM stands for Static Random Access Memory.
• It uses flip-flops to store each bit of data and does not need to be periodically refreshed to maintain the charge.
• Due to this architecture, it is significantly faster than DRAM (Dynamic RAM).
• It is more expensive and consumes more power when active compared to DRAM.
• It is commonly used as cache memory in processors because of its high speed.

Information Booster: (additional info around the correct answer):
• SRAM is volatile, meaning data is lost when the power supply is turned off.
• It takes up more space on a chip than DRAM because it requires more transistors (usually 6) per bit.

Additional Knowledge: (Information about incorrect options):
Flash Memory (Option b)
• A type of non-volatile storage that can be electrically erased and reprogrammed; used in USB drives and SSDs.
ROM (Option c)
• Read-Only Memory is non-volatile and used to store the BIOS/firmware that boots the computer.
DRAM (Option d)
• Dynamic RAM is slower than SRAM and requires constant refreshing thousands of times per second to retain data.

So the correct answer is (a)
