The evolution of System-on-Chips (SoCs) is intricately linked with the efficient management of storage and connectivity within them. This chapter gives a broad overview of various SoC components, memory, and interconnect technologies. Within the communication technologies, on-chip and off-chip communication technologies are discussed, which increased in scope and complexity with the size of the SoC as well as the homogeneity/heterogeneity of the processing units. For the memory technologies, the cache management is presented with a special focus on various parameters that accurately capture the performance.
