Was he referring to the Z state? If so, it's not really ternary logic but rather a "no result" state for cases where there is a control signal involved (e.g., in a tri-state buffer).
- mod 9y agoSo it was a small lie?
- Cyph0n 9y agoNot really, no. More like an unnecessary detail, especially if it was an introductory course on the subject. It's not like knowledge of the Z state will suddenly change how you would design systems.
- tlb 9y agoModern CPUs have phase-locked loops generating clocks for each region of the chip. These use separate pull-up and pull-down mosfets to control the frequency, so arguably ternary. Even more non-binary things happen inside DRAM and flash memory.
- Cyph0n 9y agoEhh I don't believe PLLs have a ternary component at all. I'm not an expert though. DRAM is analog-based due to the fact that the core memory unit is a capacitor, so it can't be ternary (not digital). I might agree with flash though.
