How does DRAM work?
How does DRAM differ from SRAM?
One major difference between DRAM and SRAM (Static Random Access Memory) is that DRAM requires constant refreshing to maintain its contents, while SRAM does not. This is because SRAM stores data using flip-flops, which are bistable circuits that can maintain their state until a new value is written to them. DRAM, on the other hand, requires a constant supply of electricity to maintain its stored charge, and the charge tends to leak away over time. As a result, DRAM needs to be refreshed frequently to prevent data loss.
