general description micron real ssd ? embedded universal serial bus (usb) mass storage drives provide 2gb, 4gb, 8gb, or 16gb of usb 2.0-compatible memory storage in a small form factor. the embedded usb drive is an ideal solution for applications that require low cost and high reliability. typical applications include pc caching and boot drives for embedded computing, server, and networking systems. high performance, reliability, and easy implementation make micron realssd embed- ded usbs an ideal storage solution. to consistently deliver the best possible perform- ance, the embedded usb uses only slc nand flash, and all densities use two x8 nand channels to the controller. in addition to being fast, slc nand flash offers solid reliability, coupled with ecc and wear leveling. the usb system interface is widely avail- able in many system designs and is easy to implement, enabling rapid time to market. the embedded usb consists of two tsop-packaged micron nand flash components, a usb controller, and a 10-pin usb connector on a pcb. different densities are availa- ble depending on the number of die in each package and the density of each nand flash die. the drive operates at 5v 5%. it uses industry-standard 10-pin connectors and supports usb specification, revision 2.0. it is also backward compatible with revi- sion 1.1 and can be used with operating systems that support usb mass storage class specification, revision 1.0. figure 2: functional block diagram usb controller channel 1 channel 1 channel 2 nand data bus nand data bus nand command usb connector micron nand flash micron nand flash usb protocol table 1: nominal package dimensions, density, and weight value unit height 9.6 mm width 26.6 mm length 36.9 mm density 1, 2, 4, 8 gb unit weight 4.5 g embedded usb mass storage drive (e230) general description pdf: 09005aef84053f80 eusb.pdf - rev. a 4/10 en 3 micron technology, inc. reserves the right to change products or specifications without notice. ? 2010 micron technology, inc. all rights reserved.

error management the realssd ? embedded usb incorporates advanced technology for defect and error management. it uses various combinations of hardware-based error correction algo- rithms and firmware-based wear-leveling algorithms. over the life of the drive, uncorrectable errors may occur. an uncorrectable error is de- fined as data that is reported as successfully programmed to the drive, but when it is read out of the drive, the data differs from what was programmed. see the uncorrecta- ble bit error rate table. the mean time between failures (mtbf) can be predicted based on component reliabil- ity data obtained by following the methods referenced in the telecordia sr-332 reliabil- ity prediction procedures for electronic equipment. table 3: system reliability density mtfb (operating hours) 2C16gb >1 million device hours table 4: uncorrectable bit error rate uncorrectable bit error rate (ber) 1 operation <1 bit error in 10 15 bits read note: 1. ber is measured with a write-to-read ratio of 1:1. embedded usb mass storage drive (e230) error management pdf: 09005aef84053f80 eusb.pdf - rev. a 4/10 en 5 micron technology, inc. reserves the right to change products or specifications without notice. ? 2010 micron technology, inc. all rights reserved.
