SPI NOR Flash is the electronics industry’s stable, reliable choice for code and data storage. It’s the preferred option for boot code, for instance: with the non-volatile SPI NOR Flash operating in code shadowing mode, boot code is transferred at start-up to volatile DRAM or SRAM for execution. Free of the bit errors to which NAND Flash is prone, SPI NOR Flash normally eliminates the need for error correction code (ECC) and is easier to manage. 

GigaDevice SPI NOR Flash memory products are widely used in consumer devices and PCs because of their reputation for high quality and reliability. The GigaDevice SPI NOR Flash memory product range covers all market needs, with densities from 512Kbit up to 2 Gbits, and with interfaces supporting double transfer rate (DTR) at 104MHz and single transfer rate (STR) at 133MHz. 

A new entrant to the GigaDevice range is its second-generation 1.2 V SPI NOR Flash. Featuring a 1.8 V main power supply and a 1.2 V supply for I/O lines, this product series is ideal for use with the latest SoCs fabricated on advanced process nodes below 22 nm.
