Static RAM (SRAM) | A type of Computer memory

 SRAM :-

                              SRAM is a type of semiconductor memory where the word "Static" indicates  that it does not need to be periodically refreshed to retain its data. SRAM is more expensive, but faster and significantly less power hungry than DRAM. due to a more complex internal structure,  SRAM is less dense than DRAM and is therefore not used for high-capacity, low-cost applications such as the main memory in personal computers. Static RAM is mainly used to make the CPU's cache.
