Teardown of Nikon D7000 reveals Sony sensor, more (updated)  
Wednesday, January 26, 2011 | by Rob Galbraith
A teardown of the Nikon D7000 by semiconductor and electronics analysis firm Chipworks reveals a Sony-made imager, microcontroller from Toshiba, 512MB of RAM and more. If you'd like a peek inside Nikon's latest digital SLR, photos of its Sony IMX071 CMOS image sensor and other internal components are in a blog posting on the Chipworks website.

Update, January 27, 2011: If you're puzzled by how we came up with 512MB total RAM for the D7000, here's some info that should clear up the confusion. The Chipworks posting notes they found "4 x Nanya NT5TU64M16GG 1-Gb DDR2 SDRAM" inside the camera. Nanya's specs for this memory module indicate it contains 1,073,741,824 bits. This is the same as one gigabit, and is consistent with Chipworks' description. One gigabit (Gb) - which is not the same unit of measurement as gigabyte (GB) - is  equal to 125MB. Multiply that by four, which is the number of Nanya memory modules that Chipworks found, and the result is 512MB.

The company has previously done teardowns of the Canon EOS 60D, Nikon D3100, Nikon D3S and Panasonic Lumix GH2 as well as many other products with image sensors, including the Apple iPhone 4. Photos and detailed technical reports are available on these products, for a fee.
