1. INTRODUCTION
1.1. General Description
iNAND is an Embedded Flash Drive (EFD) designed for mobile handsets and consumer electronic
devices. iNAND is a hybrid device combining an embedded thin flash controller and standard MLC
NAND flash memory, with an industry standard e.MMC 4.411 interface.
Empowered with a new e.MMC4.41 feature set such as Boot and RPMB partitions, HPI
(implemented on MLC products only), and HW Reset the iNAND e.MMC is the optimal device for
reliable code and data storage.
Designed specifically for mobile multimedia applications, iNAND is the most mature on board
SD/MMC device since 2005, providing mass storage of up to 32GB in JEDEC compatible form
factors, with low power consumption and high performance - an ideal solution for multimedia
handsets of 2.5G, 3G, 3.5G and 4G.
In addition to the high reliability and high system performance offered by the current iNAND
family of products, iNAND offers plug-and-play integration and support for multiple NAND
technology transitions, as well as features such as advanced power management scheme.
iNAND uses advanced Multi-Level Cell (MLC) NAND flash technology, enhanced by SanDisk‟s
embedded flash management software running as firmware on the flash controller.
iNAND architecture and embedded firmware fully emulates a hard disk to the host processor,
enabling read/write operations that are identical to a standard, sector-based hard drive. In addition,
SanDisk firmware employs patented methods, such as virtual mapping, dynamic and static wearleveling, and automatic block management to ensure high data reliability and maximize flash life
expectancy.
SanDisk iNAND provides up to 32GB of memory for use in mass storage applications. In addition
to the mass-storage-specific flash memory chip, iNAND includes an intelligent controller, which
manages interface protocols, data storage and retrieval, error correction code (ECC) algorithms,
defect handling and diagnostics, power management and clock control.
iNAND enables multimedia driven applications such as music, photo, video, TV, GPS, games,
email, office and other applications.
The breakthrough in performance and design makes iNAND the ideal solution for mobile handset
vendors, portable navigation and Automotive Infotainment vendors who require easy integration,
fast time to market and high-capacity.
1.2. Plug-and-Play Integration
iNAND optimized architecture eliminates the need for complicated software integration and testing
processes and enables a practically plug-and-play integration in the system. The replacement of one
iNAND device with another of a newer generation requires virtually no changes to the host. This
makes iNAND the perfect solution for platforms and reference designs, as it allows for the

utilization of more advanced NAND Flash technology with minimal integration or qualification
efforts.
SanDisk iNAND is well-suited to meet the needs of small, low power, electronic devices. With
JEDEC form factors measuring 12mm x 16mm (169 balls), 12x18mm (169 balls) and 11.5x13mm
(153 balls) compatible with 0.5mm ball pitch, iNAND is fit for a wide variety of portable devices
such as multi-media mobile handsets, personal media players, GPS devices and Automotive
infotainment (car multimedia and car navigation).
To support this wide range of applications, iNAND is offered with an MMC/SD Interface.
The MMC interface allows for easy integration into any design, regardless of the host (chipset) type
used. All device and interface configuration data (such as maximum frequency and device
identification) are stored on the device.

1.4. Functional Description
SanDisk iNAND contains a high-level, intelligent subsystem as shown in Figure 1. This intelligent
(microprocessor) subsystem provides many capabilities not found in other types of storage devices.
These capabilities include:
Host independence from details of erasing and programming flash memory
Sophisticated system for managing defects
Sophisticated system for error recovery including a powerful ECC
Power management for low power operation
1.5. Technology Independence
SanDisk iNAND uses 512 bytes as sector size. To write or read a sector (or multiple sectors), the
host software simply issues a read or write command to the device. The command contains the
address and number of sectors to write or read. The host software then waits for the command to
complete.
There is no host software involvement in the details of flash operations such as erase, program or
read. This is extremely important since flash devices are becoming increasingly complex with
current advanced NAND MLC processes. Because iNAND uses an intelligent on-board controller,
host system software will not need to be updated as new flash memory evolves. In other words,
systems that support iNAND technology today will be able to access future SanDisk devices built
with new flash technology without having to update or change the host software.
1.6. Defect and Error Management
The SanDisk iNAND contains a sophisticated defect and error management system. If necessary,
iNAND will rewrite data from a defective sector to a good sector. This is completely transparent to
the host and does not consume any user data space. In the extremely rare case that a read error does
occur, iNAND has innovative algorithms to recover the data. These defect and error management
systems, coupled with the solid state construction, give SanDisk iNAND unparalleled reliability.

e.MMC4.41 Features Overview
SanDisk iNAND e.MMC 4.41 I/F -Data Sheet
80-36-03433
2. E.MMC4.41 FEATURES OVERVIEW
2.1. Boot
iNAND supports e.MMC 4.41 boot operation modes, 1MB is size.
2.2. Automatic Sleep Mode
A unique feature of iNAND is automatic entrance and exit from sleep mode. Upon completion of
an operation, iNAND enters sleep mode to conserve power if no further commands are received.
Typically the entrance to sleep mode occurs after 200ns, max value entering sleep mode is 850ms
due to housekeeping operation. The host does not have to take any action for this to occur,
however, in order to achieve the lowest sleep current, the host needs to shut down its clock to the
memory device. In most systems, embedded devices are in sleep mode except when accessed by
the host, thus conserving power. When the host is ready to access a memory device in sleep mode,
any command issued to it will cause it to exit sleep and respond immediately.
2.3. Sleep (CMD5)
An iNAND device may be switched between a Sleep and a Standby state using the
SLEEP/AWAKE (CMD5). In the Sleep state the power consumption of the memory device is
minimized and the memory device reacts only to the commands RESET (CMD0) and
SLEEP/AWAKE (CMD5). All the other commands are ignored by the memory device.
The Vcc power supply may be switched off in Sleep state is to enable even further system power
consumption saving.
For additional information please refer JESD84-A441 section number 7.6.15
2.4. Enhanced Reliable Write
iNAND supports enhanced reliable write as defined in e.MMC 4.41 spec4.
Enhanced reliable write is a special write mode in which the old data pointed to by a logical address
must remain unchanged until the new data written to same logical address has been successfully
programmed. This is to ensure that the target address updated by the reliable write transaction never
contains undefined data. When writing in reliable write, data will remain valid even if a sudden
power loss occurs during programming.
2.5. Secure Erase
In addition to the standard erase command the iNAND supports the optional Secure Erase
command5.
The Secure Erase command differs from the basic Erase command in that it requires the iNAND to
execute the erase operation on the memory array when the command is issued and requires the
iNAND and host to wait until the operation is complete before moving to the next iNAND
operation.

e.MMC4.41 Features Overview
SanDisk iNAND e.MMC 4.41 I/F -Data Sheet
80-36-03433
The secure erase command requires the iNAND to perform a secure purge operation on the erase
groups, and copy items identified for erase, in those erase groups .
A purge operation is defined as overwriting addressable locations with a single character and then
performing an erase.
This new command meets high security application requirements (e,g, those used by military and
government customers) that once data has been erased, it can no longer be retrieved from the
device.
2.6. Secure Trim
The Secure Trim6 command is similar to the Secure Erase command but performs a secure purge
operation on write blocks instead of erase groups. The size of a write block in the iNAND device is
512B
2.7. Trim
The Trim function is similar to the Erase command but applies the erase operation to write blocks
instead of erase groups. The size of a write block in the INAND device is 512B
For additional information on the Trim function, refer to JEDEC standards No. JESD84-A441
2.8. Partition management
The iNAND offers the possibility for the host to configure additional split local memory partitions
with independent addressable space starting from logical address 0x00000000 for different usage
models. Therefore memory block area scan be classified as follows7:
Factory configuration supplies two boot partitions, each 1MB in size, implemented as
enhanced storage media and one RPMB partitioning of 128KB in size.
The host is free to configure one segment in the User Data Area to be implemented as
enhanced storage media, and to specify its starting location and size in terms of Write
Protect Groups. The attributes of this Enhanced User Data Area can be programmed only
once during the device life-cycle (one-time programmable).
Up to four General Purpose Area Partitions can be configured to store user data or sensitive
data, or for other host usage models. The size of these partitions is a multiple of the write
protect group. Size and attributes can be programmed once in device life-cycle (one-time
programmable). Each of the General Purpose Area Partitions can be implemented with
enhanced technological features.
2.9. Enhanced Write Protection
To allow the host to protect data against erase or write, the iNAND supports two levels of write
protect command8:

The entire iNAND (including the Boot Area Partitions, General Purpose Area Partition, and
User/Enhanced User Data Area Partition) may be write-protected by setting the permanent
or temporary write protect bits in the CSD.
Specific segments of the iNAND may be permanently, power-on or temporarily write
protected. Segment size can be programmed via the EXT_CSD register.
For additional information please refer JESD84-A441 standard.
2.10. High Priority Interrupt (HPI)
Many operating-systems use demand-paging to launch a process requested by the user. If the host
needs to fetch pages while in a middle of a write operation the request will be delayed until the
completion of the write command.
The high priority interrupt (HPI) as defined in JESD84-A441 enables low read latency operation
by suspending a lower priority operation before it is actually completed. This mechanism can
reduce read latency, in typical condition to below 10msec.
For additional information on the HPI function, refer to JESD84-A441 standard section 7.6.20
Note: HPI is implemented on MLC products only
2.11. H/W Reset
Hardware reset may be used by host to reset the device, moving the device to a Pre-idle state and
disabling the power-on period write protect on blocks that was set as power-on write protect before
the reset was asserted. For more information, refer to JESD84-A441 standard.
2.12. DDR I/F
Support DDR signaling to double bus performance. For additional information please refer to
JESD84-A441 standard.

VDDi
Internal
VDDi is the internal regulator connection to an
external decoupling capacitor.
5.2. Capacitor Connection Guidelines
5.2.1. VDDi Connections
The VDDi (C2/K2) ball must only be connected to an external capacitor that is connected to VSS.
This signal may not be left floating. The capacitor‟s specifications and its placement instructions
are detailed below.
The capacitor is part of an internal voltage regulator that provides power to the controller.
Caution: Failure to follow the guidelines below, or connecting the VDDi ball to any external signal
or power supply, may cause the device to malfunction.
The trace requirements for the VDDi (C2/K2) ball to the capacitor are as follows:
Resistance: =6.3 V
Dielectric: X7R or X5R
5.2.2. VCC and VCCQ Connections
All VCC balls should be connected to a 3.3V supply
All VCCQ balls should be connected either to a 3.3V or 1.8V supply
SanDisk recommends providing separate bypass capacitors for each power domain as shown in

Note: Signal routing in the diagram is for illustration purposes only and the final routing depends
on your PCB layout. Also, for clarity, the diagram does not show the VSS connection. All
balls marked VSS should be connected to a ground (GND) plane.
