In the present invention is disclosed a flash memory for simultaneous read and write operations. The memory is partitioned into a plurality of sectors each of which have a sector decoder. The sector decoder connects a plurality of main bit lines to a plurality of sub bit lines contained within each memory sector A 21 decoder is used to demonstrate the invention although other decoders including a 2M decoder and a hierarchical type decoder can be used. The memory array can be configured from a variety of architectures, including NOR, OR, NAND, AND, Dual-String and DINOR. The memory cells can be formed from a variety of array structures including ETOX, FLOTOX, EPROM, EEPROM, Split-Gate, and PMOS.
