What Is DRAM (Dynamic Random Access Memory)?

Dynamic Random Access Memory (DRAM) is a form of volatile memory used to temporarily store data in computing devices. Each bit of data is stored in a separate capacitor within an integrated circuit.

DRAM capacitors tend to lose charge over time and need a constant power supply to periodically refresh stored data and maintain its integrity, hence the term dynamic.

Dynamic RAM is cost-effective and offers higher storage density compared to Static Random Access Memory (SRAM). Although it operates at a slower speed, these features make it the preferred choice for main system memory in computers, servers, and many other devices.
