NAND Flash - The Other Half of the Story


TweakTown image content/3/0/3053_07.jpg


So far we have talked a lot about interfaces and controllers, but that is only half of the story. Recently Intel and Micron co-introduced 34nm flash memory. By shrinking the manufacturing process they were able to deliver lower cost, lower power flash memory for use in SSDs.


The next leap in flash technology will come from double data rate (DDR) flash memory. Just like the DDR used in our DDR random access memory (RAM), DDR flash will allow more data to flow and give us twice the effective speed. Samsung is leading the charge with their recently announced 30nm class DDR MLC NAND flash. The new MLC DDR flash reads data at 133 Mbps, up from 40 Mbps with Samsung's own single data rate flash.


Looking back at the information provided on Indilinx's page on the Jet Stream, we already know that Jet Stream will be able to use DDR NAND flash; at least that is what they are reporting now.
