Difference between SRAM and DRAM

SRAM		DRAM
SRAM (Static Random-Access Memory)		DRAM (Dynamic Random-Access
SRAM: Uses flip-flops made of transistors to store a single bit of data. It requires multiple transistors per bit, resulting in a more complex structure but offering faster access times.		DRAM: Utilizes a capacitor and a transistor to store each bit of data. The charge in the capacitor represents the binary state. This structure is simpler than SRAM but requires constant refreshing due to the charge leakage from capacitors.
SRAM: Volatile memory, meaning it loses its stored information when power is turned off.		DRAM: Also volatile, and it needs to be refreshed periodically to maintain the integrity of stored data.
SRAM: Faster access times compared to DRAM because it doesn't require refreshing, and data can be directly accessed.		DRAM: Slower access times due to the need for periodic refreshing and the additional time required to read and rewrite data.
SRAM: Generally consumes more power than DRAM because it uses more transistors per bit and does not take advantage of charge leakage for storage.		DRAM: Typically consumes less power due to its simpler structure and the use of charge storage.
