Memory
SRAM (Static RAM)
Memory using bistable circuits (flip-flop-like) to store bits, providing fast access without refresh.
Detailed Explanation
Each SRAM cell uses 6 transistors (6T) in a cross-coupled inverter pair. Data persists as long as power is applied, unlike DRAM which needs periodic refresh. SRAM is faster but less dense than DRAM.
SRAM access involves precharging bit lines, enabling the word line (row), and sensing the small voltage difference. Write involves driving bit lines to overpower the cell's current state.
