Consumer DRAM

Density: 4Gb Organization: 512Mx8 Speed: PB, RC Package: 78FBGA

DDR4 offers excellent performance, while enabling high-speed operations, low energy consumption and greater reliability. Samsung disproved the assertion that DRAM has reached an evolutionary wall with DDR4, which can run at a speed of 2,133 Mbps, well beyond the existing memory limit of 1,866 Mbps. Clearly, DDR4 performs well beyond previous generations of memory. Because it can operate at such a high speed, system performance is improved nearly 15%. DDR4 features advanced DRAM design technology, therefore, Samsung has been able to significantly improve its speed, while reducing noise levels. A key strength of DDR4 is that it reduces power consumption 24% compared to DDR3, by operating at a voltage of 1.2 V and adopting a Pseudo Open Drain interface. This means that, even with its increased performance, DDR4 boasts lower power consumption. In addition to power and performance improvements, DDR4’s reliability has improved significantly. DDR4 is designed to call attention to errors that occur during data transfer so that they can be resolved.
