Circuit for generating trim bit signal in a flash memory device

摘要

Disclosed is a circuit for generating a trim bit signal in a flash memory device. The circuit comprises a control unit selected by a trim bit select signal and including a programmable and erasable cell, and an output unit for outputting a High level signal or a Low level signal through the trim bit signal output terminal depending on the program cell of the control unit. Thus, as important parameters could be controlled that decide the characteristics of the chip even after the package, the characteristics of the chip could be improved and the productivity could be thus improved.
