The Chip That Let Computers Talk to Each Other

In 1966, computer memory was still being built by hand. Workers threaded tiny magnetic rings with wire, one bit at a time. It was slow, expensive, and incredibly labor-intensive. Then an IBM researcher named Robert Dennard came up with a radically simple idea: what if a single transistor and a tiny capacitor could store a bit instead? That idea became DRAM — Dynamic Random Access Memory. In this video, we explore how Dennard's deceptively simple memory cell helped replace magnetic core memory, why earlier solutions failed, how Intel turned dynamic memory into a commercial breakthrough with the 1103, and how the same basic principle eventually made gigabytes of memory cheap enough for personal computers, smartphones, game consoles, data centers, and today's AI systems. From hand-woven Apollo computer memory to billions of microscopic memory cells operating invisibly inside modern electronics, this is the story of the tiny invention that changed computing forever.
