Samsung revealed what they claim are the first flash memory chips based on the eMMC 5.1 standard which was just approved by JEDEC, the group that oversees the development of many semiconductor industry standards. eMMC is an embedded version of the MultiMediaCard standard that was once popular among digital cameras and PDAs. It allows for the NAND and controller in a device to be put into a small package on the logic board, which is a necessity when working with small mobile devices.
This eMMC is based on the eMMC 5.1 standard approved by JEDEC recently. Sequential reads and write speed of Samsung’s 64GB eMMC 5.0 flash memory were 250MB/s and 90MB/s respectively. Samsung’s 64GB flash memory based on eMMC 5.1 would offer sequential write speed of 125MB/s. Similarly, random read performance increases from 7,000 IOPS to 11,000 IOPS and random write performance increases from 7,000 IOPS to 13,000 IOPS.
As mobile devices have become more complex, there has been a need for improved NAND performance and more of such devices. eMMC 5.1 based memory also has new features that will enable further improved performance. The new eMMC also offers seamless multitasking activities including the streaming and playback of UHD (Ultra High Definition) video content. It also offers Secure Write Protection security protocol feature that ensures only its designated user’s access secured areas of the eMMC. Meanwhile the company has also released an official teaser image of its upcoming flagship device, do check it here.
