I know that it comes from the fact that NOR cells are connected in parallel to the bit lines, but I don't get why you couldn't be able to read a whole word at once on NAND memory. In theory one could make a NAND flash controller that allows the NAND to be …
WebSize and Capacity. NAND architecture enables placement of more cells in a smaller area compared to the NOR architecture. For similar process technology, the physical design of NAND flash cells allows for approximately 40% less area coverage than NOR flash cells. The lower cost per bit also contributes to the higher density of NAND memory devices. Webbit is physically written differs from the last time it was logically written. 2.1.2 Comparison to NOR Flash Memory Cells in NAND Flash are arranged in arrays of between 8 and 32 cells. Unlike in NOR Flash, the individual cells are not connected to the bit line. For this reason, NOR Flash requires more area and is slower to program and erase,
