What it is
Memory cell of a single transistor and a capacitor that is refreshed periodically. It enabled dense, cheap semiconductor memories that displaced ferrite cores.
What it led to
- The cheapening of memory that made the personal computer possible
- The Japanese and Korean memory industry (Samsung, SK Hynix) and chip trade wars
- Data-intensive workloads and AI models
