The company has suggested he chip - developed for mobile devices - is the world' first 10-nanometer 8Gb LPDDR5 DRAM.
According to the firm's announcement, it is 1.5 times as fast as the mobile LPDDR4X DRAM chips which are used in other current mobile devices.
Jinman Han, senior vice president of Memory Product Planning & Application Engineering at Samsung Electronics, said: "This development of 8Gb LPDDR5 represents a major step forward for low-power mobile memory solutions.
"We will continue to expand our next-generation 10nm-class DRAM lineup as we accelerate the move toward greater use of premium memory across the global landscape."
Meanwhile, it will also offer users a "deep sleep mode", which will cut the power usage to around half the "idle mode" of the current DRM chip.
It's said that Samsung's "functional testing and validation of a prototype" is complete, ad the company is now planning to begin mass production of the product at its factory in Pyeongtaek, Korea.
Although the chip has been announced, the company hasn't confirmed when users will see the chip begin to arrive in new phones.
