SanDisk® TransFlash™
Memory Module
The small, scalable, semi-removable
solution for next-generation embedded
flash data storage applications.
Actual Size
As flash data storage requirements continue to increase, flash storage
memory modules offer a small, scalable and semi-removable
alternative to embedded NOR and NAND components.
Based on the industry-standard serial SD™ interface,
SanDisk’s incredibly small TransFlash memory module is
ideal for designs where space is limited, as well as
storage-hungry designs demanding 32MB* or larger amounts
of embedded flash. TransFlash is perfect for today’s industrial and
consumer applications requiring a small footprint, high capacity,
scalable storage solution.
SanDisk’s TransFlash is the world’s smallest removable flash memory
storage module, measuring a miniscule 11mm by 15mm and 1mm
thick. The optimal solution for the embedded flash storage market,
TransFlash is currently available in 32MB, 64MB and 128MB capacities
(with higher capacities coming soon).
When compared to flash data storage solutions based on the
component design, semi-removable TransFlash offers system
designers and manufacturers significant advantages such as lower
overall manufacturing costs, greater design flexibility and scalability,
seamless technology transitions, and faster time to market.
Empower your designs today with SanDisk’s innovative TransFlash
memory module.
*1MB = 1 million bytes
SanDisk TransFlash. The next evolutionary
embedded flash solution.
SanDisk, the world’s largest supplier of flash data storage products, continues to lead the industry in the ongoing
evolution of application memory solutions. Our newest innovation, TransFlash, combines the low cost and small
size of component flash with the flexibility of removable media. The result is a superior flash module solution
with a wide range of capacities.
In comparing a flash component vs. a TransFlash module, the “old” component memory solution requires multiple
memory components directly soldered onto the printed circuit board. This approach creates many problems,
among them:
• Host processor managing individual memory components
• Constantly changing memory technologies requiring frequent hardware and software updates
• Limited flexibility in memory capacity without hardware re-spin
• Limited scalability
• Limited field memory upgradeability
• Requires complicated memory management and reliability algorithms
In contrast, SanDisk’s new scalable TransFlash module approach offers significant design and manufacturing
advantages, including:
• The same physical form factor (footprint) for a wide range of capacities
• On-board controller eliminates the need for host memory management and separate software
development for ECC and wear leveling
• Seamless memory component technology transitions
• Industry-standard serial interface to minimize risks (plus backwards compatibility)
• Unprecedented upgradeability and flexibility
• On-board savings in real estate
