Low Power DDR4/4X SDRAM

Low-Density Memory for AI-Enabled Devices

Many smartphones, smart vehicles, wearables, and several other IoT devices now integrate edge AI to optimize their processes. These devices require ultra-fast data processing memories to perform optimally. Low power DDR4 SDRAM especially the LPDDR4X variants are low-density memories best suited for devices enabled by edge AI. 

What Is LPDDR4?

LPDDR4 is a low-power dynamic RAM that boasts significant improvements over LPDDR3 chips. Just like with earlier iterations in the low power category, an LPDDR4 transmits data on both rising and falling edges of its clock signal. It however achieves greater bandwidth without a variation in clock frequency while utilizing less power than older generations of LPDDR units.

Winbond LPDDR4X: Unique Low-Density Memory

With newer AI-powered technologies constantly emerging in ever more compact devices, it is critical for onboard memory systems to be able to deliver high-speed data processing at low power. The LPDDR4X SDRAM is a low variant of LPDDR4 DRAM optimized for next-generation applications.

LPDDR4 includes two series: the JEDEC defined LPDDR4X (VDDQ voltage 0.6V) and LPDDR4 (VDDQ voltage 1.1V).

As for data transmission rate, the product series covers 3200MT/s, 3733MT/s, or even reaches 4266MT/s. In addition, KGD (Known Good Die) and 200-ball BGA packages are available.

Winbond Low-Density LPDDR4X Is Optimized for Emerging Applications

Winbond manufactures the best LPPDDR4 chips for newer applications across various industries. Some examples of newer applications Winbond systems are compatible with include:
