| Async SRAM has been with us since the days of the 386, and is still in place in the L2 cache of many PCs. It's called asynchronous because it's not in sync with the system clock, and therefore the CPU must wait for data requested from the L2 cache. The wait isn't as long as it is with DRAM, but it's still a wait. | |||
