Abstract
In this paper, we propose a FSOURCE circuit which requires such a small switching current that an eFuse OTP memory can be programmed in the post-package state of the PMIC chips using a single power supply. The proposed FSOURCE circuit removes its short-circuit current by using a non-overlapped clock and reduces its maximum current by reducing the turned-on slope of its driving transistor. Also, we propose a DOUT buffer circuit initializing the output data of the eFuse OTP memory with arbitrary data during the power-on reset mode. We design a 24-bit differential paired eFuse OTP memory which uses Magnachip's $0.35{\mu}m$ BCD process, and the layout size is $381.575{\mu}m{\times}354.375{\mu}m$($=0.135mm^2$).
