SD NAND is the embedded storage solution. Packaged in a compact 6×8mm BGA chip with a standard SD/SDIO interface and just 8 pins, it solders directly to your PCB — permanently, reliably, and with no mechanical slot to fail.
At Jiangsu Ruixin Microelectronics, a professional SD NAND manufacturer, we design and manufacture SD NAND chips built for the realities of embedded product development: space-constrained PCB layouts, cost-sensitive IoT BOM targets, SDIO-based MCU ecosystems that cannot support eMMC, and production lines that demand SMT-compatible components.
SD NAND is an integrated embedded storage solution that combines MLC NAND Flash, a controller, and firmware in a BGA package. It provides high reliability, stable performance, and simplified system integration, making it ideal for IoT, wearables, and other space-sensitive applications requiring robust data storage.
The key insight is in the interface: SD NAND communicates via the standard SD/SDIO protocol, the same protocol that governs conventional memory cards. This means:
Any microcontroller or application processor with a native SDIO interface can drive it directly
No proprietary drivers, no new protocol learning curve
The host sees the chip as a standard SD storage device
This is what makes SD NAND the optimal choice for resource-constrained embedded platforms where eMMC is not supported but the reliability of a soldered component is required.As an experienced SD NAND manufacturer, Ruixin also provides engineering support, PCB footprint files, and long-term supply assurance for embedded OEM projects.
