Samsung Electronics has launched the world's most powerful 12 GB mobile DRAM to power foldable phones, including the Galaxy Fold.

Samsung Electronics has launched the world's most powerful 12 GB mobile DRAM targeting foldable phones, including the Galaxy Fold.

Samsung Electronics announced on March 14 that it would begin mass production of 12 GB low-power DDR (LPDDR) 4x mobile DRAMs, whose capacity is the largest ever. The product has six 16 Gb chips, increasing its capacity 1.5-fold compared to 8 GB mobile DRAMs.


The 12 GB DRAM is larger than an 8 GB DRAM module, which is mounted on a typical ultra-slim laptop. The new chip enables users of big-screen ultra-high-resolution smartphones such as foldable phones to seamlessly run a variety of applications, the Korean semiconductor giant said.

"Mobile companies are introducing five-or-more-camera modules, multiple large displays, artificial intelligence processors, and 5G telecommunication services to next-generation smartphones," a Samsung official said. "We can significantly boost the performance of high-end smartphones by loading them with high-capacity DRAMs."

This memory product can read and write data at the speed of 34.1 GB per second, which is the fastest among mobile devices currently available. Its package is only 1.1 millimeters thick, which can make mobile devices slimmer.

Samsung Electronics is planning to meet demand for high-performance DRAMs from mobile device makers by starting mass production of the 12 GB mobile DRAMs in March, and tripling the supply of 8 GB or larger mobile DRAMs in the second half of 2019.


Meanwhile, Samsung Electronics plans to launch its first foldable smartphone model “the Galaxy Fold” in the second quarter.
