How Alpha Particles Can Break Computer Chips
This content explores how 1970s Intel DRAM memory suffered from mysterious bit flips caused by invisible radioactive contamination in chip packaging materials.
Key Takeaways
- Intel discovered that 16-kilobit DRAM chips were spontaneously flipping bits from one to zero.
- The root cause was trace uranium and thorium contamination in ceramic packaging sourced from a plant near an old uranium mill.
- Alpha particles from these contaminants ionized the silicon, creating electron-hole pairs that triggered single-event upsets.
