Message Text: Kingmax says it is prepared for the challenges of the Napa age.

Intel?s recent announcement of its new mobile platform ? Napa ? has propelled the already rapidly developing mobile technology industry into the third generation. The announcement also implies that dual-core systems will soon be available for notebooks. In just one year, Intel has exceeded Moore?s Law in the evolution from Sonoma to Napa.

The Napa architecture consists of three components, the CPU, chipset and wireless module, all of which have been updated with the new generation? the Intel 945 series chipset, Intel Core processor and Intel 3945ABG wireless module. The biggest differences between Napa and the second-generation Sonoma platform are the upgrade of the front-side bus to 667MHz, support for PCI Express x16 and DDRII 667 memory. The Intel Core will be available in single and dual-core configurations built on a 65 nm process. The Intel Pro/Wireless 3945ABG wireless module is compatible with 802.11a/b/g wireless protocols. Most importantly, the Napa platform modules are small, providing more flexibility for a wider variety of notebook designs, and the new platform provides a reduction in power consumption of 1.2W, leading to longer battery life.

If the Sonoma platform brought notebooks into the DDRII age, Napa presents another leap forward in notebook memory specifications, as DDRII 667 is expected to follow the growth of the Napa platform to become the mainstream memory of choice for notebooks. The advantage of DDRII memory in mobile platforms is its low-power advantages. However, mass production of notebook DDRII memory is no simple feat. Currently only a handful of memory manufacturers have the capacity to mass-produce DDRII 667 SO-DIMM modules.

Packaging and testing requirements for notebook DDRII 667 memory pose considerable challenges for memory makers. It is well known by now that BGA is the default packaging format for DDRII memory. What this means is that, in the DDRII era, only companies who possess substantial BGA packaging technology capabilities will be able to achieve broad market acceptance. Only those companies who have accumulated years of technology experience and possess the core BGA packaging technologies will be able to compete.

Kingmax is one of the companies who possess these advantages. Kingmax has a vertically integrated supply chain. The company operates its own packaging facilities and handles the entire manufacturing process from purchasing and dicing of wafers, testing and packaging to finished product testing. Kingmax developed BGA packaging technology eight years ago and has successfully utilized it in the mass production of its SDRAM and DDR products.

Kingmax announced its latest Venus series DDRII 667 SO-DIMM modules at the 2005 Computex Taipei exhibition. Since then, Kingmax has completed all the preparations for mass production and the Kingmax DDRII 667 SO-DIMM modules are now available on the market. This memory series provides all of the functions for the latest memory trends in terms of data transfer frequencies, application performance and compatibility.

Kingmax?s next generation DDRII memory architecture technology complies with JEDEC standards for DDRII 667 SO-DIMM high-specification memory, and supports lower working voltage design (1.8V), which can reduce power consumption by approximately 50%. With a working frequency of 333MHz, the SO-DIMM memory can take advantage of up to 5.3GB of memory bandwidth with its 200pin configuration. Additionally, integrated ODT (on-die-termination) technology maintains memory signal waves at high speeds, minimizing noise interference.
