What does SRAM stand for and its primary use?

SRAM stands for Static Random Access Memory, and its primary use is indeed for CPU caches. Static RAM differs from Dynamic RAM (DRAM) in that it does not need to be refreshed every few milliseconds, making it faster and more reliable for operations that require quick access to data. This speed is crucial in CPU caches, where data needs to be retrieved and written very quickly to ensure efficient processing.

SRAM retains data bits in its memory as long as power is supplied, allowing for quick access times that are essential for the performance of the CPU. This is why it is predominantly used in cache memory, as it improves the overall speed and efficiency of data processing by providing rapid access to frequently used data.
