WebSep 17, 2024 · RRAM is a new type of non-volatile storage technology, which can be used to realize the storage device 106 . The cache in the processor 102 is usually implemented by a static random access memory (Static Random Access Memory, SRAM), wherein the SRAM is a volatile memory. WebStatic Random Access Memory (SRAM) is the memory block which holds the data. The size of the SRAM determines the size of the cache. 2.3.2 Tag RAM Tag RAM (TRAM) is a small piece of SRAM that stores the addresses of the data that is stored in the SRAM. 2.3.3 Cache Controller The cache controller is the brains behind the cache.
