摘要
本文演示了非易失性FeRAM高速缓存对硬盘驱动器(HDD)性能的改善。首先，介绍了128Mb ChainFeRAMTM设计和满足HDD应用的电源系统设计。其次，介绍了非易失性FeRAM高速缓存的概念以及模拟和测量的HDD性能改进。通过PC mark 05和FD bench v1.01的基准测试，以及5天的PC用户数据，读写带宽分别提高到1.12倍、3.3倍和1.9倍。这些结果与使用DRAM缓存将HDD旋转速度从5400rpm提高到7200rpm的结果相同或更有效。在PC Mark05测试中，写入能量减少了25%。
A 128Mb ChainFeRAMTM and system designs for HDD application and enhanced HDD performance
This paper demonstrates the hard disk drive (HDD) performance improvement by nonvolatile FeRAM cache. First, the 128Mb ChainFeRAMTM design and power supply system design to meet HDD application are presented. Second, the concept of nonvolatile FeRAM cache and the simulated and measured HDD performance improvement are presented. The read/write bandwidth improvements to 1.12 times, 3.3 times and 1.9 times have been obtained by bench mark tests of PC Mark 05 and FD Bench v1.01, and by PC user data for 5 days, respectively. These results have been the same level of or more effective than the results of HDD rotational speed-up from 5400rpm to 7200rpm using DRAM cache. The write energy is reduced by 25% in PC Mark05 test.
