64 Mbit DDR SDRAM 4M X 16, 3.3VOLT - Details in V58C365164S

According to the latest MEMS market research report of IHS, as the market demand for broadband Internet services continued to surge, it is expected that the sales of optical MEMS market is growing strongly in 2011 and even the following years. Optical MEMS is the key part in high-speed fiber-optic network.Optical MEMS has been considered as high-value applications in MEMS market, and it is expected that the 2011 revenue of this field will grow from $169.9 million to $211.8 million, with an increase of 24.7%. IHS iSuppli's research shows that this year's growth rate is less than last year's 48.3%, mainly because of the inventory correction during the first to the third quarters. In 2010, overheated market led to inventory increasing, so this year, suppliers take actions to cut inventory and reduce production output.Sales growth will be stronger next year, and it is expected to rise 32.5% to $280.7 million. Overall, the compound annual growth rate during 2010-1015 will reach 20.5%.Optical MEMS is the key electronic componentin optical communications network which could provide high capacity and reduce costs, can be used for Internet, video and multimedia interactive and advanced digital services. Since optical fiber in-home technologies are widely used now, it is the key fact which promotes the growth of optical MEMS. Additionally, the rapid development of broadband in China and the dramatic increase of the network video flow are also the important motivate factors. Especially, the shift from non-MEMS technology to mini-MEMS based exciter to improve performance will stimulate the above growth as well.As an alternative for adding new optical fiber, optical MEMS can also be used to reconfigure the existing network. WSS ROADM can increase the flexibility of client-side interconnect, and tunable filters make the network become more agile.By 2015, the key MEMS markets will be as follows, WSS ROADM, with sales revenue to reach $279 million; VOA devices, revenue to achieve $86 million; cross connection for the optical signal from input ot output fiber, with the revenue as $31 million; tunable filters, reaching $30 million sales.MEMS-based WSS ROADM devices are the highest sales among optical MEMS. The devices' main suppliers include JDS Uniphase Corp., Oclaro Inc. and Capella Intelligent Subsystems Inc., which are all located in California, USA; Nistica Inc., based in New Jersey, is also one of its main suppliers.
