Facing the dual demands for increased storage capacity and improved energy efficiency driven by the evolution toward ultra-high-definition and highly interactive intelligent terminals, Union Memory’s new- generation eMMC 5.1 products have emerged just in time, to address market pain points with the following three core competitive advantages.
Doubled capacity for demanding performance scenarios — It is upgraded to 256GB, easily handling high-load tasks such as 4K video editing and AI computing.
Energy efficiency leap, power consumption reduction by 18% — Optimized power management significantly extends device battery life, while significantly reducing heat dissipation and operation cost.

Optimal TCO, delivering long-term value — Combining high performance with low power consumption, it can significantly lower the TCO throughout the product lifecycle.

Delivers Massive Capacity and a Performance Leap

Driven by AI, large-capacity storage has become a rigid demand in embedded applications such as consumer electronics, automotive electronics, and industrial IoT. In daily consumption and automotive electronics scenarios, applications such as high-definition audio and video contents, high-resolution games, large-scale apps, smart home camera data storage, and vehicle-mounted infotainment systems are continuously increasing the demands for large-capacity storage.

Union Memory’s new-generation eMMC 5.1 products continue the high performance of their predecessors, with sequential read/write speeds rising to 330/290 MB/s and random read/write performance reaching 33K/30K IOPS. Both product-level and system-level performances have been significantly improved over the previous generation, with particularly significant advantages in system random read/write performance. In addition to the 64GB and 128GB options, the eMMC 5.1 series now includes a 256GB version, increasing the capacity without compromising speed. This fully meets the storage requirements across a wide range of scenarios, preventing users from frequently clearing data or replacing devices due to insufficient space, and effectively reducing the users’ TCO in the long run.

Energy Efficiency Innovation, Redefining Performance Boundaries through Ultra-low Power

eMMC 5.1 products can maintain a precise balance between performance and energy efficiency through low power consumption architecture design and intelligent multi-level sleep mechanisms with both product-level and system-level power consumption optimization approaching 18%, effectively breaking the industry paradigm that “capacity upgrade inevitably increases power consumption”. Intelligent terminals equipped with eMMC 5.1 can maintain relatively low operating temperature even under demanding scenarios such as 8K video streaming and multi-application concurrency, effectively extending battery duration, and reducing device thermal design cost. To address 24/7 operational scenarios such as smart home and industrial IoT, the eMMC 5.1 products introduce an innovative multi-level sleep mechanism. In an inactive state, the device automatically enters a microampere-level sleep mode, ensuring an instant wake-up response time of less than 1 ms.

Optimal TCO, Enhanced Lifecycle Value

The TCO of a complete storage solution encompasses multiple cost factors, including procurement, energy consumption, maintenance, and replacement. eMMC 5.1 products significantly optimize lifecycle cost from procurement to operation and maintenance through the core triangle model of “large capacity + high energy efficiency + long lifespan”.

1. Large-capacity, extended lifespan design

By combining 3D NAND with dynamic SLC caching technology, the lifespan is further increased by 50% compared with the previous generation. Coupled with an intelligent wear-leveling algorithm, it offers a write endurance of 200 TBW (256 GB). Even under the demanding condition of 20 GB of daily writes on a smartphone, it ensures reliable coverage for well over 7 years, avoiding slowdown or data loss caused by storage aging.

2. Balance between performance and endurance

The dynamic mode strategy is optimized in depth, adjusting the ratio between SLC cache and TLC main storage according to the real-time workload, balancing burst write speed with long-term storage needs, and providing stability and good user experience. Overall, performance fluctuation in a dynamic mode is reduced by over 50% compared with the SLC-priority mode, while flash endurance is extended by 1-2 times compared with TLC direct-write mode, which equates to a lifespan extension of 3-10 years.

3. Reliability-driven operational cost reduction

The firmware adopts an enhanced SPOR 2.0 power-loss protection mechanism and LDPC hard-and soft-decoding error-correction algorithms, reducing the risk of data loss from unexpected shutdown by over 90%, and lowering device failure and repair rates by 65%.

Union Memory’s new-generation eMMC 5.1 products feature enhanced energy efficiency and capacity, translating into significant commercial value in typical application scenarios. In the context of an industry facing the dual challenge of data explosion and rising storage costs, the eMMC 5.1 products take extreme TCO as its core, providing intelligent terminal manufacturers with a storage solution that redefines performance without cost anxiety, helping enterprises build sustainable smart device ecosystems, and driving the multi-billion-level market into the “era of energy efficiency economics”.
