JEDEC solid state technology association recently announced for common flash update released (it), is expected to bring the removable memory card for mobile devices market new choice standard of...

JEDEC 4 standards include this update JESD220C it version 2.1, JESD223C UFSHCI version 2.1, JESD220-1 a it version 1.1 and the UME cineplex chain JESD223-1 a UFSHCI UME version 1.1, mainly aimed at the need of high performance and low power consumption of mobile applications and operation system, such as smart phones and tablets.

FS version 2.1 update, including joining equipment health status description, which provides detailed information on the service life of the equipment, will make the most of the application of it technology. Because support for preventive maintenance, especially suitable for automotive electronics field. Instruction function through the software for the more pressing priority task allocation is higher priority, which helps to improve system performance; At the same time, increase security to protect and support the modern high order required by the operating system and application of fine granularity write protection applications.

At the start of the global mobile communication conference held in Barcelona, Spain (MWC), Samsung (Samsung) declared the 256 gb of memory component doubled it memory capacity and speed, targeting high-end mobile device applications. Samsung it memory using the V - NAND flash memory chip with high performance controller, to meet the demand of the high-end smartphones, including the large size of the screen on a mobile device for ultra-high resolution (UHD) video playback and multitasking.

With a larger pattern of standard, among the UFC JEDEC incremental updates. The last major update it 2.0 was released in 2013, which is designed for the need of high performance and low power consumption of mobile applications and operation system. It v1.1 from each channel link bandwidth of 300 MB/s increased to 300 MB/s, and import the multi-channel support, for each direction to achieve data transmission of up to 1.2 GB/s transmission rate.

Samsung announced earlier this year for its high-end mobile devices with 256 gb of memory component doubled it memory capacity and speed

Released at the same time, JEDEC JESD220-2 it Card Extension Standard, on behalf of Qualcomm, Qualcomm JEDEC JC - 64.1 subcommittee chairman Hung Vuong said that this kind of pluggable memory Card Standard using existing it embedded component specifications, extended support for the mobile market. He pointed out that in terms of performance and power consumption point of view, JESD220-2 is designed for designed with the existing memory card options.

Vuong said the new standard it memory card for mobile pluggable storage options, to comply with its continuous and random IOP performance requirements. 1.0 the properties of the memory card and it it embedded component standards defined in the same 2.0, at the same time using single channel to provide two-way interface velocity of 600 MB/s. It also supports MIPI M - PHY HS - Gear3, HS - Gear2 and PWM - Gear1, and has the same characteristics with embedded it 2.0 components, such as support for multiple logical unit, clear and erasure strengthen security work, such as data security, and task management and power management functions, etc.

Vuong said, however, it is 1.0 memory card with embedded it 2.0 standard is not the same, make them be more cost effective and quicker build. In addition to the MIPI M - PHY single channel operation, it does not support hardware RESET (HW RESET) signals with startup performance. "It memory card opened a different market, to provide better performance and lower power consumption, but the equivalent of embedded application."

Samsung chief engineer Yejin Moon said, although due to 4 k or even video 8 k utilization rate increase and other factors, makes the demand for it system is higher and higher, but the power consumption of mobile industry restrictions remain.

But it system has not been able to find obvious applications such as smart phones and tablet computer market. Yejin Moon pointed out, "it will be applied to uav high-end market." This market is growing, some are built-in multiple more and more high resolution camera, thus for unmanned aerial vehicle (uav) hardware overall battery life and the life time of stress, that would be it memory function advantage effectively.
