Intel’s Word-Wide FlashFile™ memory family provides high-density, low-cost, nonvolatile, read/write storage solutions for a wide range of applications. The word-wide memories are available at various densities in the same package type. Their symmetrically-blocked architecture, voltage, and extended cycling provide highly flexible components suitable for resident flash arrays, SIMMs, and memory cards. Enhanced suspend capabilities provide an ideal solution for code or data storage applications. For secure code storage applications, such as networking, where code is either directly executed out of flash or downloaded to DRAM, the word-wide memories offer three levels of protection: absolute protection with VPP at GND, selective block locking, and program/erase lockout during power transitions. These alternatives give designers ultimate control of their code security needs.
