General Description
The Micron Parallel NOR Flash memory is the latest generation of Flash memory devices. Benefits include more density in less space, high-speed interface device, and support for code and data storage. Features include high-performance synchronous-burst read mode, fast asynchronous access times, low power, flexible security options, and three industry-standard package choices. The product family is manufactured using Micron 65nm process technology.
