Differences between DRAM and SRAM?

Answer Posted / coolmoon

SRAM (Static RAM)
Data is stored in cross-coupled inverters
Large cell - requires several transistors (6T cell standard)
Fast access time / Low density
Integrates easily into logic fab processes

DRAM (Dynamic RAM)
Data is stored in form of charged capacitors
Small cell - requires one capacitor and one transistor
“Refresh” operation required every few milliseconds
Slower access time but much higher density than SRAM
