First DDR4 SODIMMs from Swissbit: More performance, less consumption
Bronschhofen, Switzerland – November 6, 2014 – Swissbit AG present their first DDR4 ECC SODIMM at electronica. Thanks to the brand new DDR4 technology, it achieves higher data rates with the same power consumption. On top of that, it features optimized data bus termination, dynamic bus inversion, and CRC protection of the command/address bus. The Swissbit DDR4 ECC SODIMM aims at the new generation of embedded boards. Samples are available now. Series production starts in 2015.
According to their focus on the industrial segment, Swissbit opens the DDR4 portfolio with the 8GB ECC SODIMM at DDR4-2133 speed. This speed class currently marks the start of the market launch of the DDR4 standard. It already enables a performance improvement of 30% compared to the DDR3 standard. In the medium term, the DDR4 technology promises a performance increase of up to double the current DDR3-1600 data rate to DDR4-3200, with only a minimal increase in thermal power consumption. At the same time, the supply voltage has been reduced from 1.35V to 1.20V. Other features include improved data bus termination, dynamic bus inversion, internal grouping of banks, and the supply of the wordline boost voltage via the module connector. They reduce power consumption, and thus additionally reduce the heat generation of the module. A further advantage of the DDR4 standard is the error protection of the command/address bus. This allows transmission errors of the main control signals to be detected; if an error occurs, the transmission can be repeated. Thanks to 260 signal and voltage pins, users can now use modules both with and without ECC support with the same pin assignment. This compatibility simplifies the system board design and allows a more flexible system specification.
The 8GB ECC SODIMM for embedded boards is Swissbit’s first DDR4 module. With the launch of further DDR4 platforms in the industrial market, Swissbit is expanding its product portfolio to include all standard and special modules for the industrial segment.
Some background information: In order to achieve higher data rates with the same power consumption, extensive modifications to the architecture of the memory chips with DDR3 technology were necessary. The standardization group JEDEC has developed these features and specified them as DDR4. The DDR4 components standard is already released, and the module standards are mostly in the fine-tuning phase.
