By aligning flash memory with a 1.2V system on chips, engineers can reduce power conversion overhead while supporting AI servers, optical networking hardware, and IoT devices.
GigaDevice has announced the expansion of its density range for its GD25UF series 1.2V ultra-low power SPI NOR Flash, available from 8Mb to 256Mb. The development is presented as a way to meet diverse storage needs, from advanced AI computing platforms to compact, battery-operated devices. By operating at lower voltage, the series is claimed to extend battery life and support miniaturization in wearables, medical devices, and edge AI systems.
The benefit of the series is its ability to operate at lower voltage, which is claimed to help extend battery life and support miniaturization in wearables, medical devices, and edge AI systems. By aligning directly with 1.2V system‑on‑chips, the devices integrate without requiring additional level shifters or complex power management. This streamlined design reduces component count and cost while improving energy efficiency by minimizing conversion losses.
The advantages also extend to practical deployment. Larger densities up to 256Mb can support workloads in AI servers, hyperscale data centers, and fiber‑optic transceivers, while smaller densities down to 8Mb in compact WLCSP packaging are suited for IoT devices, hearables, and medical monitoring equipment. This flexibility allows the series to serve both high‑performance computing environments and space‑constrained designs.
At the feature level, the series scales up to 256Mb, supporting workloads such as code storage, high-bandwidth interconnects, and fiber-optic transmission in AI servers and computing platforms. For smaller devices, densities as low as 8Mb are offered in compact WLCSP packaging. The series supports Single, Dual, Quad, and DTR Quad SPI modes, with throughput up to 80MB/s. Compared to traditional 1.8V Flash, the operating voltage is reduced by about one-third, lowering power consumption by 50 to 70 percent. Reliability is supported with 100,000 program/erase cycles, 20-year data retention, and operating temperature ranges up to 125℃, meeting industrial and automotive standards.
The company notes that the full series is in mass production with multiple package options by company emphasizing its broader goal of supporting energy-efficient computing across applications, highlighting the series as part of its ongoing commitment to sustainable semiconductor solutions.
