A 3.3V 32Gb NAND-Flash memory with 3b/cell is demonstrated in 34nm technology. The device features a programming throughput of 6MB/s on blocks configured as 3b/cell mode and can dynamically switch up to 13MB/s in 2b/cell mode. A new quad-plane architecture and an optimized programming algorithm are adopted to achieve the design targets.
