Innodisk announced the release of its industrial-grade DDR5 DRAM modules.

The new industrial-grade DDR5 DRAM modules feature performance improvements and power savings over its predecessor, in addition to speed and storage increases.

According to the company, the JESD79-5 DDR5 SDRAM specification signaled the transition to DDR5, with improvements in capacity, speed, voltage, and ECC functions. The DDR5 specification details up to four times as much capacity per IC, raising the maximum achievable per die capacity to 64Gb and bringing the maximum potential capacity for a single DDR5 DIMM to 128GB.

DDR5 also has a theoretical maximum transfer speed of 6400MT/s, doubling the rate of DDR4. Meanwhile, the voltage has been dropped from 1.2V to 1.1V, reducing overall power consumption. A further structural change is power management is moved onto the DIMM, reducing redundant power management circuitry on the motherboard for unused DIMM slots.

Another structural change is dual-channel DIMM architecture. For DDR5, each DIMM has two 40-bit channels (32 data bits, eight ECC bits each) for the same data total with more ECC bits. Two smaller independent channels are designed to improve memory access efficiency, leading to suitable speeds with high efficiency. Innodisk currently offers DDR5 up to 32GB and 4800MT/s.

Per the company, most industries should notice the benefits of DDR5 in 5G, deep learning, AI, edge computing, smart medical, supercomputing, and mission-critical applications.
