| Small bit cell size (0.174um^2) | Large bit cell size (50um^2) | Large bit cell size (1.2um^2) |
| Supported and scalable on most advanced process nodes | Foundry specific--not portable from foundry to foundry |
Limited legacy process technologies; reverse scalable |
| Reliability- Highly reliable, no soft errors, not sensitive to oxide leakage | Reliability - Poly grow-back challenges to longer life span | Reliability - sensitive to tunnel (gate) oxide leakage for data retention |
| No extra mask / process steps | Extra mask steps | Design rule violations |
| Physical layer security | Non secure data storage | Non secure data storage |
