Title: The Blueprint Behind the Speed: A Review of JESD79-4D Rating: ★★★★★ (Essential Reading for Hardware Architects)

Unlike SRAM (cache) or flash (USB drives), DRAM is forgetful. Literally. The capacitors holding your "1"s and "0"s leak charge in milliseconds. JESD79-4D dictates that every single row of memory must be read and rewritten every 64 milliseconds (standard temperature) or 32 milliseconds (hot environment). jesd79-4d pdf
