NAND 전하트랩 플래시메모리를 위한 p채널 SONOS 트랜지스터의 특성

The Characteristics of p-channel SONOS Transistor for the NAND Charge-trap Flash Memory

초록

In this study, p-channel silicon-oxide-nitride-oxide-silicon(SONOS) transistors are fabricated and characterized as an unit cell for NAND flash memory. The SONOS transistors are fabricated by 0.13 ㎛ low power standard logic process technology. The thicknesses of gate insulators are 2.0 ㎚ for the tunnel oxide, 1.4 ㎚ for the nitride layer, and 4.9 ㎚ for the blocking oxide. The fabricated SONOS transistors show low programming voltage and fast erase speed. However, the retention and endurance of the devices show poor characteristics.
