Any of these computer architecture concepts: register file, L1/L2/L3 cache, main memory Can be implemented with any of these components: DRAM, SRAM, D-FF (flip-flops) It's common for main memory (in embedded systems) and register files to use SRAM. But you can also implement the registers with flip-flop banks, and get something bulkier but faster. I'm not sure what Intel/AMD does.
