Abstract—This paper demonstrates the hard disk drive (HDD)
performance improvement by nonvolatile FeRAM cache. First,
an array architecture and data path design of 128 Mb chain
FeRAM to meet HDD specifications, and a total power supply
system for HDD application are presented. A 1.6 GB/s read/write
bandwidth with page length of 512 Byte HDD sector size, and the
data protection against sudden power fai
