How to Free Up Space on Your iPhone or iPad, How to Save Money on Your Cell Phone Bill, How to Find Free Tools to Optimize Your Small Business, How to Get Started With Project Management. NAND is the other. The flash chips are divided into erase segments called blocks, and data is stored into these erase blocks. NOR flash memory is one of the two popular types of flash memory. NAND is best suited to flash devices requiring high capacity data storage. NOR Flash Memory Technology Overview Page 3 NOR vs. NAND Flash Density For any given lithography process, the density of the NAND Flash memory array will always be higher than NOR Flash. In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus its output is complement to that of an AND gate.A LOW (0) output results only if all the inputs to the gate are HIGH (1); if any input is LOW (0), a HIGH (1) output results. NOR flash memory is one of two types of non-volatile storage technologies. The original MOSFET (metal–oxide–semiconductor field-effect transistor), also known as the MOS transistor, was invented by Egyptian engineer Mohamed M.
