An EEPROM for microprocessors and custom logic

An EEPROM extension to a 2.5-/spl mu/ n-well CMOS technology has been developed. In this technology an EEPROM has been designed that is suitable for integration with (existing) microprocessors in a baseline 5 V technology. A 2K EEPROM memory module, usable as a building block in a cell library for custom logic, measures 3.2 mm/SUP 2/ with a memory cell area of 440 /spl mu/m/SUP 2/.
