AgigA Tech Introduces Non-Volatile DDR3 DIMMs

Sure, you already can and we have had solutions such as Gigabyte's i-RAM, released in 2005, for some time. But these products required an uninterrupted power supply that caters to DRAM's volatile characteristics. However, there is a new product, a DDR3 DIMM offered by AgigA Tech that is created as a non-volatile DIMM (NVDIMM).

The product uses an integrated controller to transfer the contents in the DRAM to also integrated NAND Flash. The briefly required power supply is provided capacitors, which do not require a separate battery. To recharge the capacitors, only "a few seconds" of regular power supply to the DIMM are required. AgigA Tech says that the data retention time in the DIMM is a remarkable 10 years.

At this time, the DIMMs are available in ample numbers as well as 1 GB, 2GB and 4GB capacities. There was no information when these DIMMS will become generally available and how much they will cost. However, do not expect these chips to be affordable for your desktop system anytime soon; AgigaTech said it is targeting RAID storage, servers, data deduplication, workstations, embedded systems, communications/networking, as well as industrial/medical as initial application fields.

    surely they are limited by the amount of times you can write to the nand chips they may come with a 5 year warranty or some such but if they were in a typical pc that gets turned off 2-3 times a day they would likely be very short lived... nice idea if your a business though.

    +1 for the business part... BUT
    NVDIMMS aren't meant for consumers, they're targeted at enterprises for raid storage applications. Such as during power interrupt, the contents of regular RAM gets copied to NVDIMMS, thus in critical applications saving a day. Yes, a typical PC gets turned on once to many times a day, but servers are meant to run without interruption for many many years.

    If you assume 100k write limit for flash, turning your PC off three times a day would limit the life of these components to just over 90 years. Not sure about your PC, but mine is likely to have been replaced a bit sooner than that!
