Silicon Motion has announced their SM2256 controller. We caught a glimpse of this new controller on the Flash Memory Summit show floor:

The big deal here is the fact that this controller is a complete drop-in solution that can drive multiple different types of flash, as seen below:

The SM2256 can drive all variants of TLC flash.

The controller itself looks to have decent specs, considering it is meant to drive 1xnm TLC flash. Just under 100k random 4k IOPS. Writes are understandably below the max saturation of SATA 6Gb/sec at 400MB/sec (writing to TLC is tricky!). There is also mention of Silicon Motion's NANDXtend Technology, which claims to add some extra ECC and DSP tech towards the end of increasing the ability to correct for bit errors in the flash (more likely as you venture into 8 bit per cell territory).
