24 What exactly is SSD for Mobile? John Geldman Director, Industry Standards Micron Technology

25 Mobile & SSD heritage Low Latency SSD/SAS Low Power UFS M-PHY Size is Right e MMC High Bandwidth January 30, 2014 M-PHY is trademark of MIPI

26 MIPI s MPHY a high bandwidth enabler UFS 2.0 supports multiple High Speed GEARS (see the M-PHY from Gear HS-G1 HS-G2 HS-G3 Transitions per second 1.25 to 1.45 Gtps 2.5 to 2.9 Gtps 5 to 5.8 Gtps UFS supports one or two lanes (for 2x bandwidth) UFS supports performance ranges from 125 MB/s (one lane of HS-G1) to 1.2 GB/s (two lanes of HS-G3) January 30,

27 The SCSI queuing architecture a low latency enabler A single threaded command sequence Note: processing the write holds off starting the next command Command 1 (write) Payload 1 Status 1 Command 2 (read) Payload 2 Status 2 A multiple threaded in-order command sequence Note: Command 1 is completed before Payload 2 Command 1 (write) Command 2 Payload 1 Command 3 Status 1 (read) Payload 2 Status 2 A multiple threaded out-of-order command sequence Note: the bus is used at maximum performance Command 1 (write) Command 2 Payload 1 Command 3 Payload 2 Status 2 Status 1 (read) January 30,

28 Low power mobile needs MPHY & SCSI Limit power draw of an idle interface M-PHY s Hibern8te state Control logical device power SCSI: START STOP UNIT command Low interface power on active transfers The differential voltage swing is 200 mv (terminated) CMOS power is proportion to C * V 2 * F Note: NAND array performance is proportional to array power: All UFS can do is minimize interface power January 30,

29 Size matters for mobile BGA is the initial UFS form factor Does 12mm x 16mm work for you? Device Types X (mm) Y (mm) Area (mm 2 ) CompactFlash msata SD (standard) M UFS UFS microsd UFS NAND package inside NAND die inside A micro card is in scope of UFS, but is only in discussions January 30,
