Samsung has just passed a new milestone in terms of random access memory (RAM or Random Access Memory). The South Korean giant has indeed started production of DDR4 components to climb to 128 GB (36 modules 4GB), a world first. It is far 3 or 4GB present in our computers.
Obviously, this super RAM does not target (yet) personal computers but will reside in corporate servers or data centers. Moreover, it will associate these bars to specific processors because at present, a chip only supports 64 GB of RAM to the maximum.
Success this feat, Samsung has used an innovation called TSV (Through Silicon Via) for connecting the die chip DRAM stacked on each other much more effectively than current devices (see diagram). The space saving and energy is obvious, which increases performance.
This new bar reaches 2400 MHz operating frequency and will be less energy than the previous 64GB strip which did not use the TSV technique. Its price is still unknown.
