Show answer & explanation
Correct answer: D
Dynamic Random Access Memory (DRAM) stores data in capacitors that leak charge over time. This requires periodic refreshing to maintain data integrity, unlike Static RAM which uses flip-flops. Additionally, DRAM is generally slower and denser compared to SRAM technology.
