NOR Flash

Flash Memories - Types

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…

Flash Memories - Introduction

Flash memory is a type of electronic memory increasingly used in a wide range of communications, consumer, computer and peripherals, and automotive applications, but which relatively few semiconductor companies can produce in volume at the low cost equipment manufacturers require. Flash memories belongs to the class of semiconductor memories called non-volatile memories, of which it is the most dynamic driving force. Semiconductor memories can b…
