Samsung KHA884901X-MC12 High-Bandwidth 8GB HBM2 DRAM Memory Detailed Analysis

In demanding fields such as high-performance computing (HPC), artificial intelligence inference, and graphics rendering—where memory bandwidth and capacity are critical—the HBM (High Bandwidth Memory) series DRAM memory has become a key hardware enabler. This is due to its unique 3D stacked architecture and ultra-high data transfer capabilities. Shenzhen Mingjiada Electronics Co., Ltd.'s KHA884901X-MC12 HBM2 DRAM memory precisely addresses mid-range high-performance storage demands with its 8GB standard capacity, stable high-bandwidth output, and outstanding energy efficiency ratio. It serves as the core choice bridging entry-level and high-end HBM products, finding extensive application in edge computing, industrial control, and mid-range GPU acceleration scenarios.

I. Core Positioning and Technical Architecture

The Samsung KHA884901X-MC12 belongs to the HBM2 Flarebolt series, serving as Samsung's flagship product for the mid-range high-performance storage market. Its core positioning emphasizes “high bandwidth, high reliability, and low power consumption,” specifically designed for scenarios requiring a balance between performance and cost. It fills the market gap between high-end HBM3 and entry-level LPDDR5. Its core technical architecture leverages the 3D stacking technology of the HBM2 standard, overcoming the performance limitations of traditional 2D DRAM to achieve dual optimization of capacity and bandwidth.

This product employs a 4-layer DRAM chip vertical stacking design paired with a Base Die substrate. Utilizing TSV (Through-Silicon Via) and micro-bump technology for high-speed interlayer interconnections, it reduces signal transmission paths to the millimeter level. This not only drastically lowers data transfer latency but also significantly enhances thermal efficiency and signal stability. A single chip integrates over 2048 micro-bumps. combined with MPGA (Micro-Package Grid Array) packaging technology, delivers 8GB storage capacity on a substrate measuring just 36mm². This achieves a 12-fold increase in packaging density compared to traditional GDDR6 memory, perfectly aligning with the demands of miniaturized, high-density hardware designs. It enables flexible integration into various compact, high-performance devices.

II. Key Performance Parameter Analysis

The core competitiveness of Samsung KHA884901X-MC12 centers on four dimensions: bandwidth, capacity, power consumption, and reliability. Each parameter has been precisely calibrated to meet high-performance demands while balancing energy efficiency and cost control. Key specifications are as follows:

1. Capacity and Bandwidth: Efficient Data Throughput Core

This product features a standard 8GB storage capacity with a 1024-bit interface design, achieving a data transfer rate of 2.0Gbps. Based on this, its peak bandwidth reaches 256GB/s—nearly five times that of traditional GDDR6 memory. Its bandwidth density of 7.1GB/s/mm² is twelve times that of conventional GDDR6, effortlessly handling multi-task parallel data processing demands. For instance, it can simultaneously process 20 4K video streams or support real-time inference for large models with hundreds of billions of parameters, effectively resolving the “data shuttling bottleneck” in high-performance computing.

Additionally, this product supports the “pseudo-channel” mode of the HBM2 standard. Each 128-bit channel can be split into two semi-independent 64-bit sub-channels. While sharing row and column command buses, these sub-channels can execute commands independently, avoiding the performance impact of restrictive timing parameters. This allows more memory cells to be activated per unit time, further enhancing overall effective bandwidth and data processing efficiency.

Operating at just 1.2V, it delivers superior energy efficiency compared to GDDR6X solutions under heavy loads while reducing power consumption by over 30% versus traditional GDDR5X memory. This makes it particularly suitable for power-sensitive applications like edge computing and automotive computing.

Additionally, the product incorporates Adaptive Power Management (APM) technology and a temperature sensor. It dynamically adjusts voltage and frequency based on device load, automatically reducing power consumption during light-load scenarios while maintaining stable performance output under heavy loads. This achieves “performance on demand,” reducing energy consumption while extending device lifespan. Furthermore, its refresh cycle of 32ms ensures data integrity while further optimizing power performance.

3. Reliability and Compatibility: Core Guarantees for Stable Operation

For reliability, the Samsung KHA884901X-MC12 supports the JEDEC JESD235B industry standard and incorporates an ECC (Error Correction Code) mechanism. It enables 16 error detection bits per 128 bits of data, effectively preventing errors during data transmission and storage to ensure data integrity. Its operating temperature range spans -40°C to 95°C, making it suitable for harsh environments like industrial control and automotive computing. System failure rates are reduced by 60% compared to traditional memory.

For compatibility, this product seamlessly integrates with mainstream GPUs like NVIDIA A100 and AMD MI100, and Xilinx Versal AI Core FPGAs. It also supports memory controllers developed by Rambus, enabling flexible integration into various hardware platforms including AI servers, edge inference devices, and industrial automation systems without requiring additional hardware modifications.
