![]() With 3D cell structures still a way out for most flash makers, steps to extend the life of 2D planar NAND were taken. The smaller you shrink the manufacturing process, the less insulation there is between flash cells, causing problems with endurance and data retention. ![]() This creates a big (or in this case small) catch-22. If you want cheaper flash, you need to harvest more dies per wafer. NAND comes from wafers, the price of which is fixed. NAND flash makes up the bulk of an SSD's bill of materials, so in order to hit lower prices, the flash has to cost less. The mainstream space is where the large volume is. We've talked about the race to the bottom. Phison also has alternative in this segment, such as the S8 and S9 controllers that are already shipping. ![]() This four-channel processor will compete in the low-cost mainstream category against Silicon Motion's SM2246EN and upcoming SM2256 controllers (the latter previewed on Tom's Hardware just a few months ago). The JMF670H controller was first demoed a year ago in Taipei, but is now coming out of its development stage. First up is JMicron, which sent over three parts in configurations we're expecting to see from partners at Computex. ![]()
