A NAND Flash PC Platform Read Write Cache
Harry Pon, K N Raja Rao · 2007
The traditional and ideal use of NAND flash has been primarily for the storage of digital images, music files, or data files in various memory cards types or USB keys. In this paper, a new non-volatile memory layer hierarchy is introduced into the PC computing platform as a NAND flash read write cache interfacing to the PCI express bus. The usage model of NAND flash in the consumer memory card environment is dramatically different from that of the PC computing environment. Consequently, the NAND flash PC platform cache usage model, work load analysis, reliability requirements and respective results was discussed.
