Samsung has announced the start of mass production of memory chips LPDDR3 (low power double data rate 3) DRAM capacity of 3 GB for mobile devices. These memory chips are designed for next-generation smartphones.

In the memory chip for mobile devices LPDDR3 DRAM capacity of 3 GB are six smallest in the industry 4-gigabit chips LPDDR3, produced by 20-nanometer technology class. They are made into a symmetrical structure of two groups of three chips each. The module has a thickness of only 0.8 mm, which would create a thin smartphones. This novelty provides data rates up to 2133 Mb / s per pin.

Chips mobile LPDDR3 DRAM memory capacity of 3 GB will be used in the most advanced smart phones, starting from the second half of 2013. Since 2014, they will be applied in a broader list of mobile devices.

Samsung 840 EVO launched a total of five capacities, namely 120/250/500/750GB and 1TB, uses 1xnm processes Toggle 2.0 TLC particles 840 to 21nm Toggle 2.0 TLC, while the 840 Pro is the 21nm Toggle MLC, in addition controller is also from the MDX replaced MEX.

The most outstanding feature of this 840 EVO should be 120GB parts. Get rid of the past Samsung 840 120GB write only 130MB / s case, the new 840 EVO 120GB written partly because one called “TurboWrite” function, and upgraded to 410MB / s, the same time part of the overall IOPS also slightly improved.

The Samsung 840 EVO 840 Pro in IOPS performance was slightly pale, but the warranty is also reduced from five years to three years.

The Roadmap from Intel or Samsung SSD Global Summit released product point of view, high-capacity SSD will be the trend of various manufacturers, as to whether it will replace the traditional hard drives, both on the current observations will continue in parallel, mainly at the same level or higher than the price of SSD traditional hard drives, so the current probability of being replaced is still quite low.

On the other hand, Samsung also released a 2.5-inch NVMe (Non-Volitile Memory Express) SSD XS1715, is the first use SFF-8936 interface 2.5-inch SSD, this series has 400/800GB and 1.6TB capacities of three, of which 1.6 TB products can provide 3,000 MB / s read speed and 740K IOPS of RANDOM Read.

Toshiba will launch in October compatible with UHS-II interface SD EXCERIA PRO series, the capacity to provide 16GB and 32GB, but also will have the most current SD card write speed 240MB / s.

Which is more than the fastest SD UHS-I interface on a 2.5 times faster, suitable used to transfer large files, and EXCERIA PRO series read speed as high as 260MB / s.

While Toshiba will also be launched in November EXCERIA Series SD card, including 32GB and 64GB, write speeds up to 260MB / s, but the read speed is only 120 MB / s.

Although this two cards compatible with UHS-II, but the speed rating is still labeled as UHS Speed ​​Grade 1, that is faster than 10MB / s, while the interface part is marked “II”, which means that supports UHS-II interface. UHS-II interface UHS-I more than a row of pins, it must be possible to use the device supports UHS-II interface, providing higher speed, the theoretical maximum speed of 312MB / s.
