256GB Memory Chip For Smartphones Is Faster Than PC SSDs


Samsung has unveiled its newest 256 GB memory chip for high-end smartphones. edded memory based on the Universal Flash Storage (UFS) 2.0 standard, for next-generation high-end mobile devices. Samsung says that its new embedded memory for mobile devices is faster than a SATA-based SSD for PCs.

The new chips offer many benefits for high-end smartphone users such as ultra-fast speed, large data capacity and compact chip size. The devices are even smaller than an external micro SD card. Also, one high-capacity 256GB UFS chip can store about 47 full HD movies. This imparts greater flexibility to smartphone designers and handheld consumer electronics.

Using the most advanced V-NAND technology, the new ultra-fast UFS chip handles 45,000 and 40,000 input/output operations per second (IOPS) for random reading and writing respectively. This makes it around two times faster than the 19,000/14,000 IOPS of existing UFS memories.


A 128GB UFS memory was announced by Samsung in February of last year. With the new device, Samsung has doubled the capacity and speed its UFS memory chips.

“By providing high-density UFS memory that is nearly twice as fast as a SATA SSD for PCs, we will contribute to a paradigm shift within the mobile data storage market,” said Joo Sun Choi, Executive Vice President, Memory Sales and Marketing, Samsung Electronics. “We are determined to push the competitive edge in premium storage line-ups – OEM NVMe SSDs, external SSDs, and UFS – by moving aggressively to enhance performance and capacity in all three markets.”

The sequential read speeds are as high as 850MB/s, which is nearly twice as fast as a typical SATA-based SSD used in PCs. This improvement comes from use of two lanes of data transfer to move data. The sequential write speeds are up to 260MB/s, approximately three times faster than high-performance external micro SD cards.

New Reference Platform For M2M, IoT

Support for Ultra HD video playback and multitasking functionality on large-screen mobile devices allows watching 4K Ultra HD movies on a split screen, while searching image files or downloading video clips.
