SK HYNIX

Semiconductor giant introduced LPDDR5X memory with HKMG process and ultra-low voltage

Mobile devices generally use LPDDR memories of several generations, which are characterized by low voltage and, therefore, very low consumption. But even that may not be enough. Company SK hynix wants to go even further and presents its new LPDDR5X memory chips, which use the HKMG (High-K Metal Gate) process. It uses a material with high relative permittivity, which reduces leakage and improves the ability to hold an electrical charge. This increases speed as a result, but at the same time reduces consumption.

As a result, the SK hynix promises a 25% reduction in power consumption, while the speed increases to 8.5Gbps, 33% more than previous 6.4Gbps models. The memories are capable of operating at a very low voltage in the range of 1.01 to 1.12 V as defined by JEDEC. Let's remember that the 6.4Gbps variants started at 1.05V. The upside should be that mobile devices with these memories can last longer on a single charge and, last but not least, will also be faster (and can do the same job in less time). SK hynix adds that while LPDDR5 is capable of transferring 10 videos at 5GB per second, the new LPDDR5X memories can handle 13 of them at the same time.
