1、cellcare,What is cellcare? Advantages How to prolong life? A series of JEDEC standard test Development status,What is cellcare?,CellCare Technology is a proprietary combination of hardware and firmware working together to improve MLC flash performance and endurance throughout the life of the solid-s

2、tate drive. Key endurance-extending features of this patented technology include, flash parameter tracking per die, which delivers reduced and controlled wear; flash management through the lifetime, which delivers reduced wear, controlled performance, improved performance, and lower write/read laten

3、cy; and advanced error correction with digital signal processing to improve data reliability and require a minimum of re-reads.,Advantages,1、24nm MLC NAND flash memory overall number of write erase (program / erase cycles) from the existing 3000 soared to 40,000, all of a sudden increase of more tha

4、n 13 times. 2、 the life of reading and writing in the late retry fromclose to 100% to less than 0.011%, the erase speed through the control can basically maintain the original level or slightly slowed down.,3、The new CellCare technology enables development of a new generation of STECs enterprise-cla

5、ss SSDs that utilizes low-cost cMLC NAND chips, while still achieving 10 full capacity random writes to the drive each day for five years, and data retention for three months (at 40C) with no degradation in performance. This equates to approximately 7.3PB of data being written to a 400GB SSD over th

6、e life of the drive.,How to prolong life?,STEC said CellCare technology is optimized for flash memory management, signal processing, signal correction, and thus to extend the functionality of the flash memory chip life.,CellCare use of adaptive flash access, signal processing, data management algori

7、thms and ECC (error checking and correction) to improve the durability of the MLC, which means that it can from those previously considered a loss and can not use the MLC unitto obtain reliable data signal.,A series of JEDEC standard test,STEC engineers performed a series of JEDEC-standard tests, in

8、cluding a program/erase endurance and data retention stress test; a stress-test-driven qualification of integrated circuits; and a SSD requirements and endurance test.,Results of the endurance testing are outlined in the table below:,Development status,Allegedly, CellCare technology has been fully embedded in STECs MLC NAND flash memory chips to create the PCI-E SAS and SATA solid state drive product
