JEDEC publishes JESD220-2 UFS Card Extension Standard

JEDEC Solid State Technology Association published JESD220-2 Universal Flash Storage (UFS) Card Extension Standard. The new removable memory card standardJESD220-2 can be downloaded at free of cost from the JEDEC website. UFS is designed for battery-operated mobile computing platforms such as smart phones and tablet computers where throughput need to be high and power consumption need to be low. UFS also supports both embedded as well as removable flash memory storage. UFS uses M-PHY and UniPro for transport and SCSI command set, supporting both sequential as well random input output operations. When it comes to throughput, a single lane UFS 1.0 card offers 600 MB/s interface speed in both directions and uses latest queuing mechanism to further increase system throughput. The highlights of the new standards as shared by JEDEC includes: 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...
