Abstract

For scale-down EEPROM, MONOS structures with the different thicknesses of gate insulators, are fabricated and the memory characteristics, such as swtching and retention characteristics are investigated. As a results, the devices with the top oxide of 20A thick were deteriorated in retentivity. However, 11V-programmable voltage for ΔV$\sub$FB/=4V and 10-year data retention were achieved in MONOS structure with the t7p oxide of 50 ${\AA}$ thick and nitride 45${\AA}$thick.
