Actually, I am wondering what this term "Interline Frame Readout CCD"
means.  As far as I know, CCD can only belong to one of the following
types: Interline transfer, Frame transfer and Full-Frame transfer.....
but not two at the same time!!  I see that this term is used in dpreview
and I believe it could be a mis-translation.

In fact, D100 uses Sony ICX413AQ CCD sensor, and its specs stated that it
is a conventional interlaced interline transfer CCD.  It claimed better
saturation, sensitivity and smear value; but nothing special about its CCD
design. http://www.sony.co.jp/SonyInfo/News/Press/200202/02-0220/
As it is a interlaced sensor design, a mechanical shutter is required.

As far as the speed, it is mostly affected by the design rather than the
underlying technology.  The recently announced Kodak 11 Meg CCD
KAI-11000CM can generate image as fast as 20 frames per second.
