What is the difference between "static RAM" (SRAM) and "dynamic RAM" (DRAM) at the circuit level?
Correct! Well done.
Incorrect.
The correct answer is A) SRAM stores each bit using a stable circuit (typically flip-flops made of transistors) that retains data as long as power is supplied; DRAM stores each bit as a charge on a capacitor, which leaks over time and must be periodically refreshed
Correct Answer
SRAM stores each bit using a stable circuit (typically flip-flops made of transistors) that retains data as long as power is supplied; DRAM stores each bit as a charge on a capacitor, which leaks over time and must be periodically refreshed
SRAM is faster and doesn't need refreshing (used for cache) but uses more transistors per bit, making it more expensive/larger; DRAM is denser and cheaper per bit (used for main memory) but requires periodic refresh circuitry to maintain stored charge.
