摘要

提出了一种新型的SONOS(多晶硅-氮氧化物-硅)非易失性闪存器件,该器件通过底部氧化物进行热孔注入进行写入,并通过薄的顶部氧化物在栅极上/栅极上隧穿进行擦除,从而降低了功耗,提高了保留率和亚阈值摆动。讨论了SONOS器件的动态特性以及与NROM技术的比较、正/反读I/sub / DS/ spl sim/ I/sub / GS/特性、编程速度和室温下的保持性能。

A novel SONOS nonvolatile flash memory device using hot hole injection for write and tunneling to/from gate for erase
A novel SONOS (polysilicon-oxide-nitride-oxide-silicon) nonvolatile flash memory device which uses hot hole injection through the bottom oxide for write and tunneling to/from the gate through a thin top oxide for erase, with reduced power consumption, improved retention and subthreshold swing is proposed. The dynamic characteristics along with comparisons to NROM technology, forward/reverse read I/sub DS/ /spl sim/ I/sub GS/ characteristics, programming speeds and retention of SONOS device at room temperature are discussed.
