"To minimize production costs and improve performance, we have applied the finest process technology a 'half generation' ahead of the industry, which is introducing 55nm and higher," said Jim Elliott, director, flash marketing, Samsung Semiconductor.
Samsung?s 51nm NAND flash chips can be produced 60 percent more efficiently than those produced with 60nm process technology. Samsung achieved this new migration milestone just eight months after announcing production of its 60nm 8Gb NAND flash last August.
The new 16Gb chip which has a multi-level cell (MLC) structure can facilitate capacity expansion by offering 16 gigabytes (GBs) of memory in a single memory card. Furthermore, by applying the new process technology, Samsung has accelerated the chip?s read and write speeds by approximately 80 percent over current MLC data processing speeds.
NAND flash memory reads and writes data in units called "pages." The 60nm NAND flash memory is designed with a 2 KiloByte (KB) page size, but the 51nm 16Gb version can process data in 4 KB pages, nearly doubling the data rate. The product also maintains the same 4 bit error-correcting code (ECC) capability as that of 60nm NAND, allowing customers to use existing system interfaces with only minor firmware upgrades. With its 4 bit ECC, Samsung eliminates the need to secure a better ECC capability to assure sufficient reliability, which would have required new costly controllers.
Samsung will offer an optimized suite of Flash software and firmware-incorporated storage devices for music phones and MP3 players to support 4KB pages. It also will provide a multi-plane performance optimization feature and wear-leveling for improved reliability. Memory cards and MP3 controllers to support the 4KB-page are already available.
