STMicroelectronics and Intel Corporation have jointly developed a common flash memory subsystem with the aim of lowering development costs for phone designers.

STMicroelectronics and Intel have jointly developed a common flash memory subsystem with the aim of lowering development costs for phone designers.

NOR flash is the memory technology of choice for the volume mainstream of the cellular-phone market segment. According to industry research firm iSuppli, 92.8% of the embedded flash memory shipping in handsets is NOR flash memory. Intel and ST provide more than 40% of the NOR flash memory in handsets today.

The move to create a ‘second source’ for NOR flash products and subsystems marks the first time that ST and Intel have worked together on common memory specifications.

The first Multi-Level Cell (MLC) NOR products based on the common specifications are 512Mbit devices independently designed and manufactured on 90nm process technology. The products are now available from the two companies.

The common subsystem specifications will also extend to 65nm MLC NOR technology and will focus on single-chip 1Gbit MLC NOR products.
