GD9FS2G8F3ALGI

Memory IC Overview

The GD9FS2G8F3ALGI is a 2 Gbit parallel NAND flash memory IC manufactured by GigaDevice. It utilizes Single Level Cell (SLC) technology and supports an 8-bit data bus width with a 128M x 8 organization. The device operates within a supply voltage range of 1.7V to 1.95V and features a page size of 2K bytes plus 64 bytes of spare area. It is housed in a 63-FBGA package measuring 9mm x 11mm, designed for industrial temperature ranges from -40°C to 85°C.

Memory IC Feature Summary

• Supports multi-plane operations for simultaneous read, program, and erase activities across independent planes.
• Includes cache read functionality to allow sequential data output while the next page is being loaded from the array.
• Provides hardware write protection via the WP# pin to prevent unintended program or erase operations.

Memory IC Applications

• Embedded code storage in mobile devices
• Data logging in industrial control systems
• Firmware storage in consumer electronics

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and temperature grade. Ensure the design accommodates the required 1.7V to 1.95V power supply rails. Confirm that the host controller supports the ONFI 1.0 compatible command set and timing requirements for reliable operation.

Memory IC Selection Notes

Select this component when a 2 Gbit capacity with an 8-bit parallel interface is required. It is suitable for designs needing SLC reliability and extended endurance. Consider the 63-FBGA footprint constraints during PCB layout. Verify compatibility with the system's operating voltage and temperature specifications before integration.

Memory IC Part Context

This part belongs to the GD9Fx2GxF3A series, which includes variants with different voltages and organizations. The 'S' designation indicates the 1.8V core voltage version, distinguishing it from the 3.3V 'U' series. All members share the same 2K+64B page architecture and multi-plane capabilities.

Memory IC FAQ

How does the cache read function improve performance?

Cache read allows the host to sequentially output data from the cache register while the device simultaneously reads the next page from the memory array, reducing overall access latency.

What is the purpose of the WP# pin?

The WP# pin provides hardware write protection. When driven low, it disables all program and erase operations to protect the data stored in the flash array.
