WebSRAM (Static Random-Access Memory) is a form of RAM that is used to store static data. It means that data stored in SRAM is active for as long as the computer system is powered up. When there are power outages, however, data in SRAM is lost. Characteristics of SRAM It does not need to be refreshed. It outperforms DRAM. It’s not cheap. WebThe cache can be disabled temporarily or permanently and used as RAM in stead. When the cache is disabled, the device runs at reduced speed. This increases the device power consumption. If you want to use the cache as cache and temporarily disable it for extra RAM at runtime, jump ahead to the Dynamic GPRAM section.
