On 2003, Samsung developed a new unified flash memory device for code and data storage: the OneNAND™. This
device has both high-speed data read function of NOR Flash and high speed write capability of NAND Flash. At date of
writing the data storage capability of NAND area is up to 16 Gb. OneNAND has a NOR interface, so the chipset detects
the OneNAND™ as NOR, while the data can be stored directly in the NAND area using multiplexed access lines.
OneNAND™ is classified as a raw NAND with internal ECC capabilities
Therefor in modern smart phones there are an only one chip for RAM, NAND, NOR flash.
In erlyer Smart phones NAND and RAM is accessed by APE(Application Processor) NOR flash accessed by CMT(Communication Processor). But in modern Smart phones there are only one processor to do all things. In other words it has APE and CMT capabilities. Such as Rapidoyawe CPU in Nokia 5800
