CIRCUIT CONFIGURATIONS AND METHODS FOR MANUFACTURING FIVE-VOLT ONE TIME PROGRAMMABLE (OTP) MEMORY ARRAYS |
摘要 |
This invention discloses a circuit trimming system that includes a one-time programmable memory (OTP). The OTP further includes a forward biased trim device connected between a voltage supply Vcc and a ground voltage wherein the Vcc having a reduced voltage substantially lower than a trimming voltage for a reversed biased device at ten volts or higher. The OTP further includes a drive circuit provided to select the OTP at a low current operating condition and for turning on a high trim current through the forward biased trim device for trimming and programming the OTP. The trimming system further includes a sense circuit connected across the forward biased trim device is for sensing a current and voltage of the forward biased trim device.
