(English Abstract)
In this paper, a 50ns 256-kb EEPROM IP for MCU (micro controller unit) ICs is designed. The speed of data sensing is increased in the read mode by using a proposed DB sensing circuit of differential amplifier type which uses the reference voltage, and the switching speed is also increased by reducing the total DB parasitic capacitance as a distributed DB structure is separated into eight. Also, the access time is reduced reducing a precharging time of BL in the read mode removing a 5V NMOS transistor in the conventional RD switch, and the reliability of output data can be secured by obtaining the differential voltage (¥ÄV) between the DB and the reference voltages as 0.2*VDD. The access time of the designed 256-kb EEPROM IP is 45.8ns and the layout size is 1571.625¥ìm ¡¿ 798.540¥ìm based on MagnaChip's 0.18¥ìm EEPROM process.
