Abstract

A 1-Mb CMOS full-featured EEPROM using a 1.0-μm triple-polysilicon and double-metal process is described. The design is aimed at developing a manufacturable 120-ns 1-Mb EEPROM with small chip size. Therefore, an advanced memory cell with high read current, an improved differential sensing technique, and an efficient error checking and correction scheme is developed. The differential sensing amplifier utilizes the output of a current sensing amplifier connected to unselected memory as a reference level. The cell size is 3.8 × 8.0 μm2, and the chip size is 7.73 × 11.83 mm2. The device is organized as either 128K × 8 or 64K × 16 by via-hole mask options. A 256-byte/128-word-page-mode programming is implemented.
