GD9AU8G8E3AMGI

Memory IC Overview

The GD9AU8G8E3AMGI is an 8 Gbit Single Level Cell NAND Flash memory from the GD9A series, manufactured by GigaDevice. It features a 1G x 8 organization with a page size of 2K + 64 bytes and a block size of 64 pages. The device supports ONFI 1.0 compatible parallel interfaces and operates within a voltage range of 2.7V to 3.6V. It includes internal ECC capable of correcting 4 bits per 528 bytes and offers industrial temperature ratings of -40°C to 85°C or -40°C to 105°C. Available in TSOPI-48 and FBGA-63 packages.

Memory IC Feature Summary

• Supports ONFI 1.0 standard for high-speed parallel data transfer
• Integrates internal Error Correcting Code (ECC) for data integrity
• Enables multi-plane operations for concurrent program and erase cycles
• Provides hardware write protection via dedicated control pins

Memory IC Applications

• Solid State Drives (SSD)
• Embedded storage systems
• Consumer electronics devices
• Industrial control equipment

Memory IC Procurement Notes

Verify the specific suffix codes against the manufacturer's datasheet to confirm package type and temperature grade. Ensure the host controller supports the required ONFI 1.0 interface timing and voltage levels. Confirm availability through authorized distributors as supply constraints may occur.

Memory IC Selection Notes

Select this component when an 8 Gbit capacity with SLC reliability is required. Ensure the design accommodates the 2.7V to 3.6V power supply range. Verify that the PCB layout supports either the TSOPI-48 or FBGA-63 package dimensions and pin configurations.

Memory IC Part Context

This part belongs to the GD9Ax8GxE3A family, which provides 8 Gbit density options. It shares architectural similarities with other GD9A series parts but differs in voltage requirements and specific package offerings. The 'U' suffix indicates the 3.3V operating variant.

Memory IC FAQ

What is the default state of the internal ECC?

Internal ECC is enabled by default after power-on but can be disabled by the user if necessary.

How does the device indicate busy status?

The R/B# pin serves as an open-drain output that goes low during program, erase, or read operations to indicate busy status.
