On Semiconductor NOR Flash
NOR Flash is a type of non-volatile memory technology used in electronic components such as computers, smartphones, and other devices. It stands for "Not OR" and is named after the Boolean logic function it performs, where the output is only low (0) if both inputs are high (1). This technology is commonly used for storage of firmware, operating systems, and other essential data that needs to be retained even when the power is turned off.NOR Flash is different from other types of Flash memory, such as NAND Flash, in terms of its structure and operation. It has a random access architecture, meaning that data can be accessed individually at any address without affecting the surrounding data. This makes it ideal for applications where fast read access is crucial.One of the main advantages of NOR Flash is its reliability and long lifespan, making it suitable for use in critical systems. However, it has a lower density and higher cost compared to NAND Flash, making it more suitable for smaller applications. Overall, NOR Flash plays a vital role in enabling the performance, reliability, and functionality of many electronic devices we use today.
