AN101 - F-RAM™ 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.

Overview

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.
