Flash controller turns noise into data

New controller from Anobit makes MLC flash behave as SLC.

The Israeli flash controller company Anobit has just released its latest controller that supports flash memory chips with capacities up to 256Gbit.

The Anobit MSP2025 delivers a 666MB/sec data transfer rate making it the highest performing low-power embedded flash controller on the market today, Anobit claims in their press release.

In addition the controller chip employs techniques to extract data that would appear as noise to other controller chips. This results in performance improvements, which again means that designers in many cases can use 2 bit MLC chips instead of SLC-technology. Or use the brand new 3 bit chips instead of 2 bit chips and achieve the same performance, but a much higher density.

The MSP2025 is the first embedded flash controller to support 20nm and sub-20nm NAND flash, resulting in a significant reduction in cost-per-bit.  As with its predecessor, the MSP2025 is also powered by Anobit’s MSP (memory signal processing) technology which is comprised of proprietary signal processing algorithms that compensate for physical limitations of the NAND flash, resulting in a dramatic improvement in endurance and performance, the company said in the press release.

With flash chips being a commodity the real difference between end products mostly lie in the way the controller logic is implemented.  There should be some good products on the market soon using this technology. S|A
