Active 3D Packaging Architecture

笔记本电脑和笔记本电脑是许多需要低功率、低容量大容量存储的应用中的两个例子。SBIR之前的一项第一阶段研究拨款研究了用3D封装固态存储器取代硬盘驱动器的可行性。具体地说，这项工作验证了两英寸乘三英寸乘五分之一英寸的PCMCIA类型2存储卡可以提供256兆字节的内存，访问时间不到1微秒，功耗可以忽略不计。这种功能既可以作为标准硬盘驱动器，也可以作为主存储器，具有成本效益。这一第二阶段项目开发并演示了256兆字节存储卡的实验室原型，其中包括数据格式化、输入输出驱动器和控制逻辑所需的有源组件，以便存储卡可以直接连接到现有的笔记本电脑和笔记本电脑。

Laptop and notebook computers are two examples of the many applications that require low-power, low-volume mass storage. A prior SBIR Phase I research grant examined the feasibility of replacing hard disk drives with 3D packaged solid state memory. Specifically, this effort verified that a two inch by three inch by one-fifth inch PCMCIA type 2 memory card can provide 256 megabytes of memory with less than one microsecond access time and negligible power consumption. This capability can be provided cost effectively both as a standard hard drive and as main memory. This Phase II project develops and demonstrates a laboratory prototype of a 256 megabyte memory card that includes the active components required for data formatting, input-output drivers, and control logic, such that the memory card can be interfaced directly to existing laptop and notebook computers.
