Flash Memory Types: NOR vs NAND Architectures
Although all flash memories use the same basic storage cell, there are a number of ways in which the cells can be interconnected within the overall memory array. The two most prominent architectures are known as NOR and NAND; these terms, derived from traditional combinatorial logic, indicate the topology of the array and the manner in which individual cells are accessed for reading and writing. Initially, there was a basic distinction between t…
