Static Random Access Memory (SRAM) is a type of random-access memory that does not require periodic refresh to retain data. It stores each bit of data using flip-flop circuits, and the data remains stable as long as power is supplied.
SRAM features ultra-fast read/write speed, low access latency, and high reliability, but its memory cells are complex in structure, with low integration density, high cost, and relatively high power consumption.
Therefore, it is mainly used in high-speed applications such as CPU L1/L2 cache, high-speed registers, and network device buffers.
