Webcache block is compared with pr_addr[5:3]. V and D are valid and dirty bits, respectively. C.C.U. stands for Cache Control Unit and oversees coordination between processor and the bus (i.e. main memory). If a block is missed in the cache, the CCU will request the block from the bus and waits until memory provides the data to the cache. WebSRAM uses bistable latching circuitry to store each bit. While no refresh is necessary it is still volatile in the sense that data is lost when the memory is not powered. A typical SRAM uses 6 MOSFETs to store each memory bit although additional transistors may become necessary at smaller nodes. Fig 1. Simplified block diagram of a static memory.
