| 摘要 |
A one-time programmable read-only memory (OTP-ROM) including a substrate, a first doped region, a second doped region, a third doped region, a first dielectric layer, a select gate, a second dielectric layer, a first channel, a second channel and a silicide layer is provided. The first doped region, the second doped region and the third doped region are disposed apart in a substrate. The first dielectric layer is disposed on the substrate between the first doped region and the second doped region. The select gate is disposed on the first dielectric layer. The second dielectric layer is disposed on the substrate between the second doped region and the third doped region. The silicide layer is disposed on the first doped region, the second doped region and the third doped region. The OTP-ROM stores data by a punch-through effect occurring between the second doped region and the third doped region.
