JEDEC releases Universal Flash Storage standard

The JEDEC Solid State Technology Association has released its next-generation storage system standard.

Going by the name of Universal Flash Storage (UFS), the new specification is, according to the company, “the most advanced specification for both embedded and removable flash memory-based storage in mobile devices such as smartphones and tablet computers.”

Gartner forecasts a 117 percent increase in mobile application downloads in 2011 from 2010, which JEDEC claims is driving a need for storage in mobile devices.

It says that the UFS standard has been created to keep up with today’s technology as it has been made especially for mobile applications and computing systems, which are high performance and are required to emit low power consumption.

The standard supports queuing features to raise random read/write speeds and the initial data throughput is said to be 300 megabytes per second. It is built on the JEDEC e-MMC standard, which has also been put in place to help with mobile devices and includes security.

The UFS standard will use the SCSI Architecture Model and command protocols supporting multiple commands with command queuing features and enable multi-thread programming.

This differs from conventional flash-based memory cards and embedded flash  features, which process one command at a time, and limits random read/write access performance.
