Product Description
The GLS85VM1002E eMMC NANDrive™ EX Series
devices (referred to as “eMMC NANDrive” in thisfactsheet) are fully integrated solid state drives. They
combine an advanced Greenliant NAND controller
and 2 GBytes of NAND flash memory in a multi-chippackage. These products are ideal for embedded andportable applications that require small form factor,
ultra-high endurance and reliable data storage.

The integrated NAND flash controller with built-in
advanced NAND management firmware communicateswith the host through the standard eMMC protocol. It
does not require any additional or proprietary software
such as the Flash File System (FFS) and Memory
Technology Driver (MTD).
eMMC NANDrive’s advanced NAND management
technology enhances data security, improves
endurance and accurately tracks the usage of theNAND flash. This innovative technology combinesrobust error correction capabilities with advanced
wear-leveling algorithms and bad block management
to extend the life of the product.

eMMC solid state drives are widely used in GPS andtelematics, in-vehicle infotainment, portable andindustrial computers, handheld data collection
scanners, point-of-sale terminals, networking andtelecommunications equipment, robotics, audio andvideo recorders, monitoring devices and set-top boxes.

eMMC NANDrive supports Single Data Rate (SDR)
and Dual Data Rate (DDR) modes, HS200 mode,
HS400 mode, boot, multiple partitions, permanent andpartial write protect, Replay Protected Memory Block(RPMB) access, Sanitize and TRIM, hardware resetand other features detailed in the eMMC 5.1 standard
specification. It is backward compatible with previous
eMMC standards.

eMMC NANDrive provides complete eMMC solid statedrive (SSD) functionality and compatibility in a 14mmx 18mm BGA package for easy, space saving
mounting to a system motherboard. With its small size,
low power consumption, strong security, reliability andruggedness, eMMC NANDrive surpasses removablestorage and discrete NAND-based products.

GENERAL DESCRIPTION

Each eMMC NANDrive contains an integrated eMMC NAND flash memory controller and NAND flash die in a
BGA package. Refer to Figure 2-1 for the eMMC NANDrive block diagram.

1.1

Optimized eMMC NANDrive

The heart of the eMMC NANDrive is the eMMC NAND
flash memory controller, which translates standard
eMMC signals into flash media data and controlsignals. The following components contribute to theeMMC NANDrive’s operation.

1.1.6 Serial Communication Interface (SCI)The Serial Communication Interface (SCI) is designedfor error reporting. During the product development
stage, it is recommended to provide the SCI port on
the PCB to aid in design validation.

1.1.1 Microcontroller Unit (MCU)
The MCU transfers the eMMC commands into dataand control signals required for flash media operation.

1.1.7 Multi-tasking Interface
The multi-tasking interface enables fast, sequential
write performance by allowing concurrent Read,
Program and Erase operations to multiple flash media.

1.1.2 Internal Direct Memory Access (DMA)
The eMMC NANDrive uses internal DMA allowing
instant data transfer from/to buffer to/from flash media.
This implementation eliminates microcontroller
overhead associated with the traditional, firmwarebased approach, thereby increasing the data transferrate.

1.2

EnduroSLC™ is a proprietary 3D NAND management
technology developed by Greenliant for high reliability
applications requiring ultra-high endurance andsuperior data retention. Using 1-bit-per-cell (SLC)
NAND configuration, EnduroSLC enabled SSDs are
ideal for write-intensive applications used in extreme
temperature, high stress environments. EnduroSLC
enabled solid state drives offer a high reliability flash
storage solution with ultra-high write endurance thatexceeds capabilities of legacy, planar SLC NAND
based products.

1.1.3 Power Management Unit (PMU)
The PMU controls the power consumption of theeMMC NANDrive. The PMU dramatically reduces thepower consumption of the eMMC NANDrive by putting
the part of the circuitry that is not in operation intoSleep mode.
The Flash File System handles inadvertent powerinterrupts and has auto-recovery capability to ensure
the eMMC NANDrive’s data integrity.

1.3

1. Manages and optimizes the data access of flash
media
2. Provides flash media wear leveling to spread
flash writes across all memory address space toincrease the longevity of flash media
3. Keeps track of the data file structure
4. Manages system security for the selectedprotection zones

1.4

Advanced NAND Management

eMMC NANDrive’s integrated controller uses
advanced wear-leveling algorithms to substantially
increase the longevity of NAND flash media. Wearcaused by data writes is evenly distributed in all or
select blocks in the device that prevents “hot spots” inlocations that are programmed and erased extensively.
This effective wear-leveling technique results in
optimized device endurance, enhanced data retention
and higher reliability required by long-life applications.

1.1.5 Error Checking and Correction (ECC)
The ECC technology uses advanced algorithms todetect and correct errors, ensuring data integrity andextending the SSD lifespan.

GLS FS0019 Rev. 01

SMT Reflow Consideration

Preprogrammed NAND devices have temperature
limits due to data retention. The EnduroSLC eMMC
NANDrive family can withstand multiple passes of
SMT high temperature process without losing data.
Using Greenliant’s recommended reflow profile during
production will help prevent damage to the device andensure better retention of any preprogrammed datathrough the surface-mount soldering process. See therelevant
datasheetsectiondescribing
therecommended reflow temperature limits.

1.1.4 Embedded Flash File System
The embedded flash file system is an integral part ofthe eMMC NANDrive. It is integrated in the controller’s
firmware that performs the following tasks:
