2 advance information 4 gbyte nandrive gls85lp1004b ?2010 greenliant systems, ltd. s71420-02-000 05/10 product description the gls85lp1004b nandrive? solid-state drive (ssd) is a high-performance, fully-integrated, embedded flash solid state drive. it combines an integrated nand controller and 4 gbyte of mlc nand flash in a multi-chip package. this product is ideal for solid state mass storage applications offering new and expanded functionality while enabling cost effective designs. ata-based solid state mass storage technology is widely used in portable and desktop computers, digital cameras, music players, handheld data collection scanners, cellular phones, pcs phones, pdas, handy terminals, personal communicators, robotics, audio recorders, monitoring devices, and set-top boxes. greenliant nandrive is a solid state drive designed for embed ded ata/ide protocol systems and supports standard ata/ide protocol with up to pio mode-6, multi-word dma mode-4 and ultra dma mode-6 interface. the built in microcontr oller and file management firmware communicates with ata standard interfaces; ther eby eliminating the need for additional or proprietary software, such as flash file system (ffs), on the host. the gls85lp1004b nandrives provide complete ide hard disk drive functionality and compati- bility in a 14mm x 24mm lbga package for easy , space saving mounti ng to a system mother- board. it is a perfect solution for portable, consumer electronic products requiring smaller and more reliable data storage. the nandrive provides a wp#/pd# pin to protec t critical information stored in the flash media from unauthorized overwrites. pre-programmed with a 10-byte unique serial id, nandrive allows users to program an additional 10 bytes of id space to create a unique, 20-byte id for greater system security. nandrive ssd is available with advanced nand management technology, a nand memory management technology that enhanc es data security, significantly improves endurance, and accu- rately predicts the rated life span of nand flas h devices. advanced nand management technol- ogy combines nand controller hardware error correction, advanced wear leveling algorithms, and bad block management to extend the life of the product.
advance information 4 gbyte nandrive gls85lp1004b 3 ?2010 greenliant systems, ltd. s71420-02-000 05/10 general description each nandrive contains an integrated nand cont roller and nand flash dies in a lbga pack- age. refer to figure 1 for the nandrive block diagram. performance-optimized nandrive the heart of the nandrive is the nand controller which translates standard ata signals into flash media data and control signals. the following co mponents contribute to the nandrive?s operation. microcontroller unit (mcu) the 32-bit risc architecture transfers the ata/ide commands into data and control signals required for flash media operation. power management unit (pmu) the power management unit controls the power consumption of the nandrive. the pmu dramat- ically reduces the power consumption of the nandrive by putting the part of the circuitry that is not in operation into sleep mode. the flash file system handles inadvertent power interrupts and has auto-recovery capability to insure nandrive data integrity. for regular power management, the host must send an idle_immediate command and wait for command ready before powering down the nandrive. sram buffer a contributor to the nandrive performance is an sram buffer. the buffer optimizes the host?s data transfer to and from the flash media. embedded flash file system the embedded flash file system is an integral part of the nandrive. it contains mcu firmware that performs the following tasks: 1. translates host side signals in to flash media writes and reads. 2. provides flash media wear leveling to sp read the flash writes across all memory address space to increase the longevity of flash media. 3. keeps track of data file structures. 4. stores the data in flash media upon completion of a write command. the nandrive does not do post-write operat ions, except for when the wr ite cache is enabled by the host command. serial communication interface (sci) the serial communication interface (sci) is designed for manufacturing error reporting. during the design process, always provide access to the sci interface in the pcb design to aid in design validation. multi-tasking interface the multi-tasking interface enables fast, sustai ned write performance by allowing concurrent read, program, and erase operations to multiple flash media devices.
4 advance information 4 gbyte nandrive gls85lp1004b ?2010 greenliant systems, ltd. s71420-02-000 05/10 error correction code (ecc) high performance is achieved through optimiz ed hardware error detection and correction. internal direct memory access (dma) the nandrive uses internal dma allowing instant data transfer from buffer to flash media. this implementation eliminates microcontroller overhead associated with the traditional, firmware- based approach, thereby increasing the data transfer rate. nand flash the nandrive family utilize standard nand flash fo r data storage. becaus e the re-flow process can alter the nandrive content, do not program the gls85lp1004b nand before the reflow pro- cess. advanced nand mana gement technology advanced nand management technology balances the wear on erased blocks with an advanced wear-leveling scheme which prov ides a minimum of 7 million host write cycles. advanced nand management technology tracks the number of program/erase cycles within a group. when the host updates data, higher priority is given to the less frequently written erase blocks; thereby, evenly distributing host writes within a wear-leveling group. the product also supports a global wear-leveling feature which can be enabled or disabled by the host command. when the global wear-leveling is enabled, the wear-leveling is performed both across and within the groups. please contact green liant for more informat ion about this feature. by default, global wear-leveling is enabled. advanced nand management technology enhances nandrive security with password protection and four independent protection zones wh ich can be set to read-only or hidden.
