    Anti-Vibration Fill is Now Available in Cervoz Industrial RAM Module

    An effective option to protect your RAM module in the harsh environment In real-world industrial computing applications, more and smaller embedded devices are installed in harsh environments with constant shock or vibrations. The RAM modules inside these devices may be vulnerable to these impacts, causing poor contacts and connection. Hence, Cervoz is now offering a value-added technology, Anti-Vibration Fill, to enhance the robustness of our DRAM modules. It is done by filling epoxy resin between the edges of PCB and RAM chips, therefore preventing the solder joints from coming loose. Anti-Vibration Fill is now available for Cervoz Industrial RAM Module upon request. Standard Series: DIMM and SO-DIMM Series (0°C~70°C) Wide Temperature Series: DIMM and SO-DIMM Series (-40°C~85°C) Server Series: DIMM and SO-DIMM with ECC and ECC with Registered DIMM Anti-Vibration Fill provides extra endurance for RAM modules installed in critical applications, such as in-vehicle computing, machine automation, military and so on

    Cervoz Launches M336 Family with Power Loss Protection Technology

    Cervoz's new M336 Family is industrial storage in MLC NAND flash, available in 2.5" SSD and mSATA form factors. In the real industrial world, users can frequently have embedded computers installed in harsh environment with unstable power supply. Cervoz has designed the cutting edge 2.5” SSD and mSATA flash module with Power Loss Protection function dedicated for the storage of embedded computers installed in these critical applications. Cervoz M336 Powerguard Flash Module provides additional power during unexpected power loss in order to complete current flash write operation, moreover to protect firmware, mapping table integrity. It is suitable for critical industrial applications, such as factory automation, machine automation, networking, server/cloud, in-vehicle, medical and surveillance. Main Features of Cervoz M336 Family Durability and Stability: Cervoz Powerguard series is designed with tantalum capacitors with wider temperature operation capability, stability in power output Smallest PLP Solution: Cervoz Powerguard made it possible to achieve PLP in 2.5” SSD and mSATA flash module. Up to 40X Discharge Time than Standard SSD: Up to 250ms discharge time For product details, please visit the following links: M336 Industrial 2.5" SATA SSD with Powerguard Function M336 Industrial mSATA Embedded Module with Powerguard Function

Technology

  • Powerguard (Power Loss Protection)

    Powerguard is a Power Loss Protection  (PLP)  technology developed by Cervoz. The Powerguard function provides additional power during an unexpected power outage to complete current flash write operation, moreover to protect firmware, mapping table integrity. Cervoz designs the Powerguard flash modules with additional tantalum capacitors to store these extra charges. Take Cervoz Powerguard mSATA for example, the integrated tantalum capacitors are permanently charged with 12V and maintain the power as long as data saving of the mSATA is still in progress. Cervoz Industrial Powerguard SSD includes capacities from 32GB~512GB and Powerguard mSATA embedded module from 16GB~64GB. It is suitable for critical industrial applications, such as factory automation, machine automation, networking, server/cloud, in-vehicle, medical and surveillance. The benefits for selecting Cervoz Powerguard flash module include Better durability and stability The Powerguard series is designed with tantalum capacitors with wider temperature operation capability, stability in power output and greater storage capacity comparing to traditional electrolytic capacitors. Various form factors to choose from Cervoz Powerguard made it possible to achieve PLP in 2.5” SSD and mSATA flash module. Up to 40X discharge time than standard SSD Up to 250ms discharge time

  • Flash Module with DRAM Buffer

    The purpose of designing an additional DRAM chip into the flash module is to increase both performance and endurance. Performance : A DRAM chip in a flash module has exactly the same function as a cache in a hard disk.  Whilst the flash module is in operation the controller throws small data into the DRAM chip for immediate responses; the DRAM chip acts as a directory that assists the controller to allocate data to the assigned positions.  Therefore it shortens the response time and increases the performance. Endurance : Comparing Flash Storage to DRAM, DRAM does not have any limitation of program/erase cycles, whereas Flash Storage does.  Every time when the controller tries to program a sector of data into Flash Storage, it needs to erase a whole block of Flash before re-programming it.  However with the DRAM buffer small data can be collected to a certain amount before delivering to the Flash Storage which reduces the program/erase times to the flash chips, and therefore increases the endurance.  

  • Reliability-Optimized MLC (Cervoz Reliance Series)

    Cervoz Reliance Series utilizes our “Reliability Optimized-MLC (RO-MLC) Technology”.  We adopt specialized firmware to control MLC NAND flash which only uses the strong pages of MLC NAND as storage; the technology is manipulated at the block level, and with each block's capacity halved by treating it as SLC.   As a result, RO-MLC improves its performance by a substantial margin: Data retention is increased 5 times, and most importantly reliability is 10 times higher than conventional MLC NAND Flash.  RO-MLC offers higher density solutions at lower costs compared to conventional SLC NAND Flash, and at the same time optimizing its reliability and performance.     Cervoz’ unique technology has made our Reliance Series (RO-MLC Technology) an extremely high price-performance ratio, and the price is only double than MLC.  In return performance, data retention and reliability are more than double (SLC is typically around 4~6 times higher in price than MLC).  Our Reliance Series is a perfect solution for semi-industrial & industrial applications that require moderate to high read and write cycles while also demanding cost effective solutions.   Cervoz offers various flash modules with the RO-MLC technology, including 2.5” SATA SSD, CompactFlash Card, and CFast Card.
