Programmable latches that include non-volatile programmable elements

摘要

A non-volatile programmable latch (210) has a fuse (F1) connected between a non-ground voltage terminal (212) and an output terminal (OUT). A NMOS transistor (110) is connected between the output terminal and ground. An inverter (120) has an input connected to the output terminal and an output connected to the gate of the NMOS transistor. A diode connects the output terminal to the non-ground voltage terminal (212) to prevent a charge build up on the output terminal when the power is off.
