Crucial introduces NVDIMM memory
Micron company Crucial comes with nvdimms for servers. This memory combines dram and nand on a single module. This means that the memory must offer the speed of dram, but must continue to store important data in the event of a power failure, for example.
Nvdimm stands for nonvolatile dimm and the memory sits in the ddr4 memory slots of servers. Crucial’s 288pin bars offer a speed of 2133MT/s and a bandwidth of 17GB/s. The memory works on a voltage of 1.2V. In the event of a power failure or other interruption, the system controller sends a signal to the module so that the data from the dram can be written to the non-volatile memory.
When the power is restored, the controller ensures that the data is written back to the dram, so that the system can continue with it. Crucial sells the nvdimm as a separate module and in a 2.5″ form factor in combination with a PowerGem capacitor from AgigA Tech, which provides the memory temporarily with energy in the event of a power failure. For now, Crucial only offers 8GB nvdimm, just like Micron According to Micron, 16GB versions are on the way.
