1. DNA memory I/O Future of computing & unattended bio-monitoring
George Church, Harvard Medical School
NEW IDEAS
“DNA computing” so far focused on computing (slow relative to silicon). This project, in contrast, explores one of the few working sub-nanometer input/output, memory & manufacturing processes. The major challenge is integration with silicon computing while maintaining the nano-size advantages.
