Toshiba's logical block addressing (LBA) interface for NAND flash reportedly has received support from Samsung Electronics in collaboration against the Intel-championed Open NAND Flash Interface (ONFI), according to market sources.
But Samsung said it is still watching closely the development of different NAND flash interfaces.
Neither Samsung nor Toshiba is a member of the ONFI Working Group, which now has over 50 members jointly developing a standardized NAND flash interface. Unlike ONFI, Toshiba has single-handedly developed what it calls LBA-NAND technology.
The market sources pointed out that as the NAND flash segment heads towards the sub-50nm processes and the embedded market, it has become ever more important to have an interface that can simplify the controllers' handling of the NAND flash.
The sources said Toshiba is expected to volume produce LBA-NAND solutions in the second half of 2007, while ONFI, despite having developed its 2.0 version, has yet to finalize its standard.
