(English Abstract)
In this paper, we design an 8-bit eSuse OTP (one-time programmable) memory based on a 0.35§­ BCD process using differential paired eFuse cells which can sense BL data without a reference voltage and also have smaller sensing resistances of programmed eFuse links. The channel widths of a program transistor of the differential eFuse OTP cell are splitted into 45§­ and 120§­. Also, we implement a sensing margin test circuit with variable pull-up loads in consideration of variations of the programmed eFuse resistances. It is confirmed by measurement results that the designed 8-bit eFuse OTP memory IP gives a better yield when the channel width is 120§­.
