SRAM static RAM SRAM is like DRAM on steroids. Since it stores its data in capacitors that don't require constant recharging to retain their data, it performs better (though it is pricier to produce). SRAM is typically used for secondary caches because its speed falls somewhere between that of DRAMs and a CPU-based cache (typically 8ns to 20ns, as opposed to 60ns to 80ns for DRAM).
