Magnetoresistive Wafer Scale Memory with On Board Search/ Cache Functions

本计画将分析并实验验证晶圆级、非挥发性、磁阻式记忆体与平行搜寻能力与快取能力。 由于磁阻存储器是非易失性的，非常密集，并且可以非常快地制造，因此它们非常适合于存储大型非易失性文件，例如数据库中的文件。 在晶片的每个有源管芯上包括搜索硬件可以将搜索加速10，000倍。 此外，板上缓存可以加速通用读写操作，允许晶圆级存储器取代当代存储器层次结构的所有组件。 在这个项目中，正在确定芯片区域到存储器、高速缓存和搜索硬件的最佳分配。 一个典型系统的电源和总线性能正在实验验证。

Wafer scale, nonvolatile, magnetorsisitive memories with parallel search capability and caching capability are being analyzed and experimentally verified in this project. Because magnetoresistive memories are nonvolatile, are very dense, and can be made very fast, they are well suited for storage of large nonvolatile files such as those in data bases. The inclusion of searching hardware on each active die of a wafer can speed up search by a factor of 10,000. In addition, on-board caching can speed up general purpose read-write operations, allowing the wafer scale memory to replace all components of a contemporary memory hierarchy. In this project, an optimum allocation of chip area to memory, cache, and search hardware is being determined. Power and bus performance for a typical system is being verified experimentally.
