Abstract

The tunnel barrier engineered charge trap flash (TBE-CTF) non-volatile memory using CRESTED tunneling barrier was fabricated by stacking thin $Si_3N_4$ and $SiO_2$ dielectric layers. Moreover, high-k based $HfO_2$ charge trap layer and $Al_2O_3$ blocking layer were used for further improvement of the NVM (non-volatile memory) performances. The programming/erasing speed, endurance and data retention of TBE-CTF memory was evaluated.
