Micron Embeds Error Correction on Flash Memory Chips

Typically what makes up a good solid state drive is the controller it is running. Companies like SandForce make some of the best controllers and are often times drives using one are the only ones to consider. Controllers ensure the SSD can last a long time and that any bad cells are easily taken care of, among other things. Micron seems to be wanting to take away some of the responsibility from controllers by embedding error correction directly on the flash memory chips. The new chips are called ClearNAND and each one has a 24-bit error correction engine built right in. This means each chip will be able to focus on error correction which will leave the controller able to do other things, like delivering even more speed.

Micron says the new ClearNAND chips are available now in 25nm sizes and come in 8 to 32GB packages for Standard ClearNAND and 16 to 64GB for Enhanced ClearNAND. The difference between the two is that Standard ClearNAND is aimed at portable media players while Enhanced will see usage in computers.
