Memories That Last
A new scheme to write data into next-generation memory chips requires considerably less resources to write data safely into memory than current systems require.

An experimental method of writing data into next-generation memory chips developed by A*STAR Data Store Institute researchers is more efficient and requires fewer resources than traditional means.
The researchers say they created an alternative approach to storing data on non-volatile memory (NVM) technologies, which will likely succeed current computer memory devices because of their ability to maintain data in the memory even after the computer has been powered off.
NVM devices use different materials than existing memory technology and thus require different data-writing processes and storage. The process used to organize data is especially important to the proper storage and retrieval of information, so the researchers adapted a version of the B+ tree architecture for use in NVM to organize memory data. The data is separated into critical and reconstructable data, and reconstructable data can be derived from the critical data, which is written into the memory first, so the researchers prioritized the consistency of the critical data.
The new tree data architecture can be 96% more efficient than other methods when used as a system specifically optimized for NVM, says A*STAR researcher Jun Yang.
