WebDec 10, 2002 · The DRAM core (i.e., what is pictured in Figure 2) remains essen-tially unchanged. Every DRAM chip is equipped with pins (i.e., very short wires), each one of which connects the DRAM to one of many possible bus-ses. Each bus is a group of wires that carry electrical signals; busses connect the CPU, memory controller, and DRAM chips. Pins are WebAnswer (1 of 3): This is going to blow your mind, but actually the DRAM storage array at the heart of every synchronous DRAM, is an asynchronous device.
