A 70nm 16Gb 16-level-cell NAND Flash Memory

Abstract

A 16 Gb 16-level-cell (16LC) NAND flash memory using 70 nm design rule has been developed. This 16LC NAND flash memory can store 4 bits in a cell which enabled double bit density comparing to 4-level-cell (4LC) NAND flash with the same design rule. New programming method achieves 0.62 MB/s programming throughput.
