OneNAND Flash Devices Combine Best of NOR and NAND

Samsung’s OneNAND Flash memory devices combine the ultra-high density of NAND-based devices with the read performance usually associated with NOR technologies. The result is increased system performance with no need to change controllers: existing hardware platforms can be simply modified.

The devices will find applications in diverse areas, including embedded systems, set-top boxes, GPS, digital TVs, handsets and other mobile applications. They can achieve sustained read rates of up to 108MB/s to optimise application functionality and are available in single-chip densities from 512Mb up to 4Gb.



With OneNAND, designers can use their existing chipset’s NOR interface to communicate directly with the Flash memory, eliminating the need for a separate NAND device. In addition, the devices have faster read/write performance that cannot be attained with NOR Flash alone. This is achieved through the use of a synchronous burst read interface and asynchronous write host interface which enables a sustained write performance of 10MB/s.



Available in 63-ball FBGA packages, the devices are based on Single-Layer Cell (SLC) technology. They incorporate automatic 2-bit EDC/1-bit ECC, and Samsung supplies software support in the form of Flash drivers and file systems, Extended Sector Remapper and Transaction File Systems, for all major OS platforms.

Product Specifications

Density	Org	Operating Voltage	Sync Clock	Package
512Mb	x16	1.8V/3.3V	66MHz	BGA
1Gb	x16	1.8V	66MHz	BGA
2Gb	x16	1.8V	66MHz	BGA
4Gb	x16	1.8V	66MHz	BGA

Embedded solutions designers will benefit in particular from the devices’ lower cost-of-use, generated not just by a 30% lower purchase cost, but also decreased PCB footprint. Suitable for both code and data storage, OneNAND devices also exhibit dramatically (100x) lower energy consumption than traditional NOR implementations.
