Abstract
This invention provides a 2-level BL-hierarchical NAND memory architecture and associated concurrent operations applicable to both 2D and 3D HiNAND2 memory arrays. New Latch designs in Block-decoder and Segment-decoder with one common dedicated metal0 power line per one 2N-bit dynamic page buffer (DPB) formed in corresponding 2N broken-LBL metal1 line capacitors for Program and per one 2N-bit Segment DPB formed in corresponding 2N local LBL metal1 line capacitors for Read are provided for performing concurrent and pipeline operations of multiple-WL Program, Read, Erase-Verify, and Program-Verify in dispersed Blocks in a same or multiple different NAND planes with much enhanced array flexibility and multiple-fold performance improvements.
