Abstract: For triple-level or quad-level 3D NAND flash memory, narrowing the Vth distribution of each state without influencing page program performance is one of the challenges. Considering this ...
Abstract: We present PLC (Penta-level cell, 5 bits/cell) NAND flash memory using 3D charge-trap-flash (CTF) cell. To achieve PLC cell distribution with proper cell read margin, program noise and short ...
