High capacity flash memory

. SanDisk’s product uses 43nm process technology and enables 64Gb memory in a single die. The company has also produced an advanced x4 controller which manages the performance requirements of the x4 memory. The memory chip combines with the controller chip in a multi chip package. The 64Gb x4 flash memory chip was codeveloped on 43nm technology with Toshiba and jas a 7.8Mb/s memory write performance. The x4 controller incorporates an error conrrection code scheme, developed for use in storage systems. Khandker Quader, SanDisk’s senior vice president, memory technology and product development, said: “The development of X4 memory and controller technologies is a major milestone for flash memory storage that will provide significant long term benefits to SanDisk and play a critical role in future nand flash scaling. 64Gb x4 is the result of numerous key innovations, and demonstrates SanDisk’s leadership in driving multi bit flash memory with performance and cost suitable for storage intensive applications such as music, movies, photos, gps, games and more.”
