DRAM
The Invention of On-Demand Data
In the mid-1960s, IBM researcher Bob Dennard developed the world’s first one-transistor memory, calling it “dynamic random access memory,” or DRAM.
Finally, mainframes could be outfitted with short-term memory to act as a buffer to the data stored on disk drives.
The memory chips would hold information the computer was working on right then, so it could go back to the disk drive only when it needed something new.
This vastly sped up the process of accessing and using stored information.
DRAM instantly made computer memory smaller, denser and cheaper, all while requiring less power.
