Samsung claims fastest mobile chips for phones, tablets
Samsung is now mass-producing what it said is the world's fastest mobile memory, an embedded MultiMedia Card (eMMC) that comes in 16GB, 32GB, and 64GB densities for next-generation smartphones and tablets.
Samsung's new eMMC Pro memory boasts an interface speed of 400MB/sec, an almost three-fold improvement over its current embedded memory.
The new eMMC Pro chips, which support the eMMC version 5.0 standard now nearing completion at JEDEC, will boost boot and application load times. The chips will enable much faster multi-tasking, web browsing, application downloading, and file transfers, as well as high-definition video capture and playback. They are also highly responsive to large-file gaming and productivity apps, according to Samsung.
"With timely mass production of our ultra-fast eMMC Pro line-up offering a more than 10X performance increase over external memory cards, Samsung will accelerate the spread of high-end mobile devices as the market for devices with larger screens and more multimedia functionality expands even further," KyongMoo Mang, vice president of memory marketing for Samsung, stated in a statement.
The eMMC Pro memory cards are based on 64Gbit, 10- to 19-nanometer-class NAND flash.
In 32GB and 64GB densities, the eMMC 5.0 memory chip has a random read speed of 7000 IOPS (inputs/outputs per second), and a random write speed of 7,000 IOPS (in cache on mode, without host overhead). In addition, the new eMMC chips have sequential read/write speeds of 250MB/sec and 90MB/sec, respectively. By comparison, Samsung's current eMMC Pro chips (based on the 4.5 specification) offer up to 2,000 IOPS random write and 3,500 random read IOPS, and 150MB/sec sequential read and 50MB/sec write rates.
Samsung's 16GB, 32GB, and 64GB eMMC 5.0 devices come in 11.5mm by 13mm packages, making them suitable for mobile devices where space on the printed circuit board is extremely limited.
