Thread: SanDisk released the world's first memory card X4

SanDisk has announced the beginning of the industrial production of flash memory, based on advanced proprietary technology X4. This innovative technology allows you to record in one cell, four bits of data that is twice as much as you can record in a cell memory chip MLC NAND. The new chips are manufactured on 43nm process technology, their volume reaches 64Gbit, that is, these chips are flash memory chips are manufactured with the highest density. SanDisk is going to produce technology-based X4 8GB and 16GB memory card, SDHC, and 8GB and 16GB cards Memory Stick PRO Duo ™.

"Development and commercialization of technology, X4 represents an important milestone for the industry of flash memory", ─ said Sanjay Mehrotra president and chief operating officer of SanDisk. ─ "With technology, X4, our task was not only reduce the cost of production of memory with 4 bits per cell, but also to ensure the requirements of reliability and performance to industrial cards that use MLC NAND. Our team of design and development, which includes experts from world-class used its extensive experience in the study of high-speed designs with 2 and 3 bits per cell, and work closely with our key partners in product design and an entirely new and powerful algorithm for error correction to ensure reliable operation. These intensive efforts have led to the emergence of powerful new patents and know - and demonstrated how SanDisks relentless pursuit for innovation, which leads to the ever-increasing use of flash drives in consumer applications, such as music, video, photos, games and numerous third-party applications.

According to analysts, the creation of flash memory with 4 bits per cell is a necessary step in the development of industry. This technology is used in bulk devices, demonstrating a cost advantage in production compared with flash memory, which allows you to record 2 bits per cell. NAND industry continues to evolve very rapidly, and the adoption of this technology is essential to remain competitive.
