AN101 - F-RAM(TM) AS ONE-CHIP SOLUTION FOR CODE AND DATA MEMORY APPLICATIONS
AN101 reviews the memory requirements for both code and data, and the design considerations for combining them in a single F-RAM device.
Applications for memory technologies are generally divided between executable code and data tasks. Executable code requires that the memory is nonvolatile and retains the code under all conditions. Data tasks require that the memory access for read and write operations are fast, simple, and unlimited. Memory for data tasks can be either volatile or nonvolatile depending on the application. The traditional choice of memory for executable code has been ROM-based technologies, while for data tasks, RAM-based technologies. F-RAM, one of the nonvolatile RAM products from Cypress, provides a unique advantage of combining both executable code and data in a single memory.
Dear valued customer,
Thank you for choosing our products. They come with all the know-how and passion that our engineers have put into it. As you probably already know, Cypress is now Infineon. This is a major step for our company, but also for the good of you.
