目前的手机行业有个重要特征:在所有手机购买者当中,有三分之二是原有手机使用者更换新的手机,新用户仅有三分之一。由于推进现有用户对手机的更新换代的关键在于具备新颖功能的高端手机,因此手机厂商将大部分研发资源投入于此,但他们也把为高端手机所研发的解决方案应用于低端的手机。为了同时满足高、低端手机应用的需求,Spansion 公司发展出 NOR+ORNAND 新型存储架构,以高灵活性力抗传统方案。Spansion 公司无线解决方案事业部执行副总裁 AmirMashkoori 表示,NAND+SDRAM 架构在手机设计中非常的普遍,然而该架构存在着慢启动的过程。相对来说,基于 NOR 架构的解决方案通常是一个快速、及时的启动过程,可以带来更好的灵活性,再配合用于数据存储的ORNAND 闪存,可以实现极佳的手机性能。Amir Mashkoori 也指出,采用 NAND+SDRAM 这一解决方案时,往往是限制在高容量范围。在这种情况下,厂商就很难在低端手机上降低成本,另外还有一些厂商采用闪存卡来解决数据存储的问题,但这似乎不是一个最好的方式。
The current mobile phone industry has an important feature: two-thirds of all mobile phone buyers are experiencing the replacement of new handsets by only one-third of new users. As the key to advancing the replacement of existing handsets by mobile phones is the high-end handsets with novel features, handset makers invest most of their research and development resources, but they also apply the solutions developed for high-end handsets to low-end handsets . To meet the needs of both high-end and low-end handsets, Spansion has developed NOR + ORNAND’s new storage architecture that is highly flexible against conventional solutions. AmirMashkoori, executive vice president of wireless solutions at Spansion, said that the NAND + SDRAM architecture is very common in cellphone designs, but there is a slow-start in the architecture. In contrast, a NOR-based solution is usually a fast, timely boot process that provides greater flexibility and ORNAND flash for data storage for excellent handset performance. Amir Mashkoori also pointed out that the use of NAND + SDRAM solution is often limited to high-capacity range. In this case, it is very difficult for manufacturers to reduce the cost of low-end handsets. In addition, some manufacturers use flash memory cards to solve the data storage problem, but this does not seem to be the best way.
