MLC = multi layer chip]]>Feb 6th 2008 2:14PMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/
MLC is multi-level cell. It means that you can store multiple bits per cell, for 2-bits per cell applications, it's one of 4 possible logic levels (00, 01, 10, 11)

MLC is obviously higher density, but slower to program]]>Feb 6th 2008 2:45PMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/Feb 6th 2008 4:01PMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/Feb 6th 2008 6:21PMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/Feb 6th 2008 1:56PMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://infiniteadmin.com/index.php/slc-versus-mlc-nand-devices/]]>Feb 6th 2008 1:58PMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/
This is way more important for SSDs than for memory cards though, right?]]>Feb 6th 2008 2:04PMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/Feb 6th 2008 1:58PMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/Feb 6th 2008 2:27PMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/Feb 6th 2008 2:32PMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/Feb 6th 2008 2:40PMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/Feb 6th 2008 2:42PMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/
still don't understand the mentality behind that]]>Feb 6th 2008 6:25PMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/Feb 6th 2008 7:23PMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/I know that with bits the numbers we see are 8 times bigger and looks good.
Otherwise, am i missing something with this particular tech ?]]>Feb 6th 2008 6:38PMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/It s written twice in the article, so please forgive or rectify my ignorance.]]>Feb 6th 2008 6:41PMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/Feb 7th 2008 12:29AMhttp://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/http://www.engadget.com/2008/02/06/sandisk-unveils-a-16-gigbit-3-bits-per-cell-flash-chips-plans/Feb 7th 2008 11:55AM
