A 4GB Xbox 360 Folks in the market for a 4GB Xbox 360 should point their browser to Amazon. The online retailer is offering a $50 credit R4 Card with the purchase of the $199 console. Surprisingly, the credit isn't restricted to games, and applies to most merchandise sold by Amazon. That's a lot of Blueberry Muffin Tops.

As in the DSi, IHS believes the apps processor in the 3DS is manufactured by Sharp and is labeled as being produced in Japan. The Sharp assumption comes from the similarity in markings on the silicon die inside the chip, resembling those from the Nintendo DSi. Similar pattern matching on die markings R4 Card is commonly used to determine chip provenance. It is also likely this apps processor was custom designed for Nintendo by another chip intellectual property and design company. An analysis of this apps processor suggests it delivers significantly higher performance than the apps processor in the DSi.

The main reason for the increased cost is that the NAND flash memory content of the 3DS has increased by eight times to 16Gbits (2GBytes),Mobile Power Station, up from 2Gbits (256Mbytes) in the DSi. The NAND flash memory found in the 3DS torn down by IHS is from Samsung Electronics Co. Ltd., and is an embedded multimedia card (eMMC) device, which enables easier implementation and shorter design cycles than conventional flash. Such memory R4 Card is usually available from multiple sources.More interestingly and potentially problematic is the multi-chip memory IC from Fujitsu employed in the 3DS that includes 512Mbits of fast cycle random access memory (FCRAM), which appears to be a proprietary technology of Japan's Fujitsu."As a rule, most electronic system designers employ memory products that are available from multiple sources in order to reduce supply risk and to guarantee the best pricing," Rassweiler noted. "However, Nintendo's decision to buy the device from sole-source Fujitsu adds supply chain risk, and limits Nintendo's capability to drive costs down on a major component."
