The SSD Review The Worlds Dedicated SSD Education and Review Resource | 
Today the doors were opened to the showroom floor of the Flash Memory Summit. We had the opportunity to meet with Silicon Motion, where they had on display their very popular SATA 3 controller, the SM2246EN and the DRAMLess model, the SM226XT, as well as the new SM2260 and SM2256 controllers.
A large portion of the Silicon Motion display was dedicated to the current SATA 3 controller, the SM2246. Being showcased along side this controller was the vast amount of manufacturers who are currently implementing this controller in their solid state drives. Take a look at the images below for an overview.
Our next stop was with the new SATA 3 controller, the SM2256. We previewed this controller previously, which you can read more about here. This controller is designed to support 1y/1z nm TLC NAND as well as the up and coming 3D NAND. The SM2256 is said to feature their NANDXtend technology, which alleges to deliver 3X NAND P/E cycles for a SSD. Silicon Motion has listed the estimated read and write speeds to support up to 540 MB/s and 460 MB/s, respectively. We were told that we can expect to see this controller used more readily in consumer drives by the end of 2015.
Next up was the SM2260, a PCIe 3.0 SSD controller that is compliant with NVMe 1.2 specifications. Also supporting the 1y/1z nm MLC/TLC NAND, this controller was listed to allow drives to reach read and write speeds of up to 2200 MB/s and 1100 MB/s, respectively. It was also told that this controller can also support ONFI 3.0, Toggle 2.0 and asynchronous NAND. We were told that we can expect to see this controller being used at the consumer level by the beginning of next year.
Stay tuned for more coverage of Flash Memory Summit 2015!
