Hi all; LG Electronics HDTV consumer equipment uses SDRAM, not RDRAM:
LG Electronics sells a lot of HDTV equipment, don't you wonder what kind of DRAM is going into it? If you look at the completed product it doesn't say. The user doesn't need to know that sort of thing. So you have to dig a bit deeper...
It turns out that LG Electronics has a System IC division, and they sell controller ICs that can be used for HDTV &c. Are these what LG Electronics uses in their HDTV equipment? I'd guess so, but there's no certainty. Anyway, let's take a look at the SIC division of LGE and see what kind of memory they're using. Here's their page that covers Digital TV and Set top boxes:

Advanced VSB Receiver
* The LGDT3102(Advanced VSB Receiver) is an ATSC compliant single chip VSB receiver that demodulates, equalizes, and corrects error of ATSC 8/16 VSB and ITU-T 2/4/8/16 VSB modulated signals.
VSB Receiver
* The LGDT3101 is an ATSC compliant single chip VSB receiver that synchronizes, equalizes, and corrects error of ATSC 8/16 VSB and ITU-T 2/4/8/16 VSB signals. The key functions of LGDT3101 are as follows.
HDTV Video Decoder
* The LGDT1101 is an advanced single-chip video processor for digital television applications implementing ATSC and DirecTV standards. Key functions of this chip include transport demultiplexor, video decoder, video display processor, 2-D graphic/OSD processor, memory controller, host interface, NTSC/PAL encoder and triple video DACs. The solution is optimized at the product level for HDTV and HDTV tuner applications.

The LGDT3102 and LGDT 3101 don't use memory directly. Instead, they connect to memory through the LGDT1101 chip:

And the LGDT1101 uses 16MBytes of cheap SDRAM:
The LGDT1101 requires 16Mbytes(8Mx1Mx16 or 4x2M32 @108MHz) as external SDRAM memories.

P.S. The reason for running this down is that TMF had this post, and I became interested:
