When computers were large and hard drives were considered a luxury, operating systems and programs could fit entirely in memory and operated without recourse to external drives. Over time, an appeal to the hard disk has become imperative not only when loading programs into memory, but also to record and upload intermediate data. The work went slowly. Today, the principle of computing in memory without regular recourse to external drives back into fashion. This requires working with the scientific and statistical data. Any power failure during long computing require a new download data.
To save the data in memory in case of emergency situations powered suggested several options for the so-called memory NVDIMM. And if earlier it was enough to attach the battery to the unit, now being developed variants of memory modules, which next to the DRAM chips are placed flash memory chips NAND-type. In case of power failure information is rewritten in the nonvolatile memory of the RAM . Such memory three years ago, promised to create the company Micron. This development should be based on the controller and the technology of the original developer - AgigA company. Today Micron introduced the promised memory.
For release Micron produced modules NVDIMM DDR4-2133. Also, the modules will be produced NVDIMM standard DDR3. The capacity of the first copies 8 GB RAM and 8 GB SSD in the outer module. Also, an external module installed backup power source in the form of supercapacitors (ultracapacitors). Energy stored in supercapacitors enough so that in case of power failure overwrite the data from the RAM to the SSD. Related Products :
