1.1. General Description
SanDisk iNAND combines SanDisk’s advanced MLC NAND flash with SanDisk’s controller and flash management
technology, providing a highly reliable, high performance on-board mass storage device.
Designed specifically for mobile multimedia applications, iNAND is the most mature on board SD/MMC device
since 2005, providing mass storage of up to 8GB in JEDEC compatible form factors, with low power consumption
and high performance that are an ideal solution for multimedia handsets of 2.5G and up.
MLC NAND Flash is the ideal storage medium for portable, battery-powered devices. It features low power
consumption and is non-volatile, requiring no power to maintain the stored data. It also has a wide operating range
for temperature, shock and vibration.
SanDisk iNAND is well-suited to meet the needs of small, low power, electronic devices. With form factors
measuring 11.5mm x 13mm, 12mm x 16mm and 12mm x 18mm, JEDEC compatible and 169, 0.5mm ball pitch,
iNAND is fit for a wide variety of portable devices like multi-media mobile handsets, personal media players, GPS
devices and more.
To support this wide range of applications, iNAND is offered with an SD Interface. The SD interface is widely
adopted by all leading industry chipsets, and provides a 4-bit high-speed data bus for maximum performance. For
compatibility with existing controllers, the iNAND offers, in addition to these interfaces, an alternate
communication-protocol based on the SPI standard.
These interfaces allow for easy integration into any design, regardless of which type of microprocessor is used. All
device and interface configuration data (such as maximum frequency and card identification) are stored on the
device.
The SanDisk iNAND provides up to 8 GB 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, wear leveling, and clock control. Figure 1 is a block diagram of the SanDisk iNAND with SD
Interface.
