Flash memory-based security rolls for handsets

To address growing wireless requirements for more robust security, Spansion is sampling what it claims is the first flash memory subsystem that provides security protection from viruses, attacks and service thefts on handsets.

The flash memory subsystems based on its proprietary MirrorBit architecture employ Spansion Secure technology, which is said to provide the highest level of commercially available protection with hardware-based encryption for mobile handsets.

Stronger protection
Traditionally, security in handsets has been handled in software and the baseband processor, which are inherently vulnerable to system attacks. By providing security in the same physical package as the memory, Spansion says its flash memory subsystems offer stronger protection when accessing the flash memory and the valuable data and content stored there.

They safeguard across multiple zones of memorysuch as separate, secured areas for the user, for the operator, for content rights objects and for the handset manufacturerwith the potential to assign up to 16 zones.

These MirrorBit products protected by Spansion Secure will be offered to customers in a Spansion multichip package (MCP). Depending on the handset configuration, the Spansion MCP would include: Spansion MirrorBit NOR flash memory, Spansion MirrorBit ORNAND flash memory, Spansion 7000C Processor, pSRAM and/or DRAM.

Volume production is targeted for Q2 2007. Pricing depends on the configuration.
