What Is Asynchronous Dram
Asynchronous DRAM is an older type of DRAM used in the first personal computers. It is called “asynchronous” because memory access is not synchronized with the computer system clock. Modern PCs use SDRAM (synchronized DRAM) that responds to read and write operations in synchrony with the signal of the system clock. Why was it phased out? When a program issued an instruction to access data in asynchronous memory, the data was still accessible on the system bus some time later....
