The M18 flash memory operates at the same bus frequency as next-generation cellular chipsets up to 133MHz. This speeds user application execution because the interaction between the chipset and memory operation is faster than in the 130nm version. With write speeds of up to 0.5MB/second, the M18 supports 3MP (mega pixel) cameras and MPEG4 video.
The new chip is also available in a denser package, with 256MB and 512MB chips shipping. Intel can stack two 512MB chips for a total of 1GB of storage. Note that NAND chips are available in densities of up to 4GB.
Several phone vendors are testing the M18 chip, including Sony Ericcson Mobile Communications and NEC.
