The new removable memory card standard standardizes functionality that aligns with the popular UFS embedded device standard. JESD220-2 is available for free download from the JEDEC website. UFS is a high performance interface designed for use in computing and mobile systems such as smart phones and tablets where power consumption needs to be minimized. Its high speed serial interface and optimized protocol enable significant improvements in throughput and mobile system performance. The new UFS card standard provides a leading-edge removable storage solution while maintaining sequential and random IOPs performance that is critical for future mobile markets. Even using a single lane the UFS 1.0 card offers 600 MB/s interface speed in both directions and a state-of-the-art queuing mechanism to further increase system throughput. Features of the UFS card are the same as those defined in the UFS 2.0 embedded device standard: Based on the UFS 2.0 standard and compatible with the UFS HCI 2.0 standard Supports MIPI® M-PHY® HS-Gear3, HS-Gear2 (optional), and PWM-Gear1 A detailed mechanical definition is defined by the JEDEC MO-320 outline Features common to embedded UFS 2.0 devices: Support for multiple logical units, each with configurable characteristics Reliable write and background operations Secure operations such as purge and erase to enhance data security Includes write protection options, including permanent and power-on write protection Provides task management and power management functionality To optimize for cost, complexity, and assist with rapid implementation of the new UFS 1.0 card standard, product designers and engineers should note the following key areas of simplification from the embedded UFS 2.0 standard: MIPI M-PHY single-lane operation HW RESET signal not supported in UFS card Ref_clock of 26Mhz and 19.2Mhz only VCCQ supply eliminated Boot capability not supported at this time “JEDEC’s new UFS card standard offers many of the features and much of the same high-end functionality as the UFS embedded device standard, but in a convenient, removable card format that would be well suited for most mobile devices,” said Mian Quddus, Chairman of the JEDEC Board of Directors and the JC-64 Committee for Embedded Memory Storage and Removable Memory Cards. He added, “JC-64 is dedicated to fulfilling the storage requirements of the mobile industry by offering product designers a range of options to better meet their needs.” Industry Support Samsung: “Embedded UFS has been proven to deliver the best performance and highest power efficiency of any storage in the mobile industry,” said Kenny Han, vice president, NAND product planning, Samsung Electronics. “It is only natural that this exemplary performance is being passed on to removable cards in extending the functionality of consumer mobile devices. The new UFS card standard will more than meet the needs of technologies that are the vanguard of the mobile industry today like 360-degree video and Drones with multiple 4K/8K recording cameras as well as smartphones which are beginning to evolve into intelligent hubs for IoT and mobile environments.” 7 / 14 UFS Card Form Factor Information Design Concept of UFS Card • Shark is strongest and fastest fish in the sea.

    Bringing Order to Chaos: Barrier-Enabled I/O Stack for Flash Storage YOUJIP WON and JOONTAEK OH, Hanyang University, Korea JAEMIN JUNG, Texas A&M University, USA GYEONGYEOL CHOI and SEONGBAE SON, Hanyang University, Korea JOOYOUNG HWANG and SANGYEUN CHO, Samsung Electronics, Korea This work is dedicated to eliminating the overhead required for guaranteeing the storage order in the modern IO stack. The existing block device adopts a prohibitively expensive approach in ensuring the storage order among write requests: interleaving the write requests with Transfer-and-Flush. For exploiting the cache bar- rier command for flash storage, we overhaul the IO scheduler, the dispatch module, and the filesystem sothat these layers are orchestrated to preserve the ordering condition imposed by the application with which the associated data blocks are made durable. The key ingredients of Barrier-Enabled IO stack are Epoch-based IO scheduling, Order-Preserving Dispatch,andDual-Mode Journaling. Barrier-enabled IO stack can control the storage order without Transfer-and-Flush overhead. We implement the barrier-enabled IO stack in server as well as in mobile platforms. SQLite performance increases by 270% and 75%, in server and in smartphone, respectively. In a server storage, BarrierFS brings as much as by 43× andby73× performance gain in MySQL and SQLite, respectively, against EXT4 via relaxing the durability of a transaction.

  • White Paper Introduction to the Universal Flash Storage Assocation
    White Paper Introduction to the Universal Flash Storage Assocation Executive Summary Universal Flash Storage (UFS) is the next generation, high-performance non-volatile storage standard. The UFS standard is defined by JEDEC and incorporates standards from the MIPI® Alliance (M-PHY and UniProSM) for data transport. UFS utilizes the SCSI Architecture Model supporting multiple commands, including command queuing which enables multi-threaded programming. UFS further supports features of eMMC, the JEDEC embedded storage memory format introduced in 2006. The MIPI M-PHY combines high speed SerDes I/O (up to 5.8Gbps per lane) with multiple operating states to achieve very low power consumption. Building on elements of existing standards will hasten the adoption of UFS by simplifying development and deployment at all levels - from ICs to firmware, system software, test and measurement. The Universal Flash Storage Association (UFSA) is chartered to promote UFS and certify compliance and compatibility of UFS products. Copyright © 2013 Universal Flash Storage Association Universal Flash Storage Association Introduction Introduction Mobile platforms use Non-volatile memory for application (typically embedded on the circuit board) and user storage (embedded and/or removable). Storage devices have to supply fast data transfers of large multimedia files such as video, music and photos as well as actively running multiple applications. Application performance depends heavily on multi-threaded memory transfer rates. Universal Flash Storage (UFS) is the next generation, high-performance Non-volatile storage standard. [1] The UFS standard is maintained by JEDEC, relies on the MIPI® Alliance M-PHY and UniProSM for transport and borrows from the SCSI command set.

The latest UFS interface protocols are optimized for efficient throughput, system performance and reliability. When using UFS solutions, power consumption is reduced due to the near- zero idle power level which, when combined with the Mobile Industry Processor Interface (MIPI)1 power-saving specifications, significantly reduces device power consumption. UFS standards also adopt the well- known Small Computer System Interface (SCSI)2 Architecture Model and command protocols that support multiple simultaneous commands and command queuing features to enable highly efficient multi-thread programming. This is a significant difference compared to legacy flash- based memory cards and embedded flash solutions which can only process individual commands, thereby limiting random read/write access performance. The UFS card is the leading technology solution for removable storage that delivers superior sequential and random read/write performance—critical for modern connected devices storing content such as drones, 360-degree devices with multiple 4K/8K recording cameras or sensors, as well as smartphones and tablets.

  • SD Card Compatiblity
    Frequently Asked Questions Memory Card CARDS - I need to reformat my memory card, which method should i use? If you have a digital camera it is better to format your card in the camera. If you are using the card in a device other than a camera, we recommend the formatting of the card using a card reader, as described below: If you are using the card in two different devices with different formats (e.g. a Digital Camera and a MP3 player) we would advise you to use two separate cards. If formatting in the Card Reader (WARNING: FORMATTING CAN & WILL DELETE ALL DATA) please see you device or camera manual before proceeding with a format. Be aware, by default Windows will format a memory card of 2GB or higher capacity to FAT32.

  • Hacking Hardware with a $10 SD Card Reader by Amir “Zenofex” Etemadieh, CJ “Cj 000” Heres, Khoa “Maximus64” Hoang
    Hacking Hardware With A $10 SD Card Reader by Amir “Zenofex” Etemadieh, CJ “cj_000” Heres, Khoa “maximus64” Hoang www.exploitee.rs Introduction Hardware hacking is increasingly important as more devices become connected. Systems are moving beyond standard hard drives and CPUs and security professionals find themselves at a loss without purpose built tools. This whitepaper aims to solve the biggest challenge facing a security professional that is looking at a hardware device: acquiring the target. To that aim, this paper contains information on reading and writing eMMC flash devices through the use of an SD Card reader/writer. Techniques for learning how to recognize eMMC flash, identifying the correct eMMC pinout, attaching to eMMC flash within an embedded device, and selecting the correct USB SD card adapter for use in reading/writing to flash will be addressed. Properly equipped, security professionals should gain the ability to read the code from targets and use that in their standard analyses. We urge readers to read this entire paper before attempting to utilize this technique as there is crucial information spread throughout and, as with all hardware, a misstep could break the target hardware. Prior work There have been many different papers and presentations on auditing hardware in the past, and several of them went into the topic of acquiring the code from the target. One such example comes from Micah Elizabeth Scott (@scanlime). On her blog, Micah discussed how she went about reverse engineering an eMMC flash pinout from a Nintendo DSi console. She stated that her intention was to build a passive sniffer to view the CPU’s attempts at reading and writing from flash1.
