Chuangfeixin (CFX)'s OTP IP is adopted in different generations of logic and HV technology (0.18/0.16/0.13/0.11 um and 90/65/55/40/28 nm). The required voltage for OTP bit cell programming can be supplied from internal charge pump or external VPP pin. The bit cell is programmed by applying a high-voltage pulse across the gate and substrate of the thin oxide transistor to break down the oxide between gate and substrate. Before programming, a blank OTP array comes with all bits reading as "0". After programming, an OTP bit cell will to be read as "1".
