What is SRAM?
Static Random Access Memory (SRAM) is a type of RAM used in various electronic applications including toys, automobiles, digital devices and computers. Static RAM or SRAM only holds its contents while power is applied. It differs from dynamic RAM (DRAM) in that DRAM must use refresh cycles to keep its contents alive. SRAM holds data as a static ‘image’ as indicated by the name, until written over or lost from powering down. SRAM is more expensive, faster and more power-efficient than DRAM for most uses. However, its internal structure also makes it less dense, and therefore a less ideal candidate for the main memory inside personal computers. Instead, SRAM is utilized for critical, secondary uses such as fast cache memory for central processing units (CPUs). CPU cache can significantly boost a computer’s overall performance with a rather small footprint of dedicated memory. Compared to DRAM, SRAM is more power-efficient when idle. However, overclocking the CPU can negate this power-sav
