    Samsung Unveils LPDDR6 Memory with 10.7 Gbps Speed

    Key Takeaways

    1. Samsung is set to release new LPDDR6 modules with speeds of 10.7 Gbps, using a 12 nm process.
    2. The new LPDDR6 modules will provide a 21% reduction in power usage due to lower core voltages and Dynamic Voltage Frequency Scaling.
    3. LPDDR6 may not significantly improve throughput compared to existing 10.7 Gbps LPDDR5x modules.
    4. Future enhancements could lead to data transfer rates reaching up to 14 Gbps as the technology develops.
    5. The earliest integration of LPDDR6 is expected in smartphones and laptops in 2024, likely with Snapdragon 8 Elite Gen 6 and AMD Medusa Point models.

    Samsung has recently hinted at the arrival of new LPDDR6 modules, being among the first manufacturers to do so after JEDEC completed the standard this year. These modules are rated to reach speeds of 10.7 Gbps and are built using a 12 nm process, although the exact details of the node are not disclosed. Samsung asserts that these modules will achieve up to 21% reduction in power usage due to lower core voltages and Dynamic Voltage Frequency Scaling, which helps decrease power consumption during low workloads.

    Comparisons to Previous Technology

    Interestingly, Samsung already produces 10.7 Gbps LPDDR5x modules on the same node, meaning the new LPDDR6 may not significantly improve throughput. However, since LPDDR6 is still quite new, manufacturers might not fully exploit its capabilities in the initial versions. Looking ahead, we could see data transfer rates reaching up to 14 Gbps as the technology evolves.

    Future Product Integration

    The press release did not mention specific products that will incorporate these LPDDR6 modules. Most of the current smartphone SoCs have already been released with LPDDR5X memory, suggesting that the earliest implementation we might witness will come later next year, probably along with the Snapdragon 8 Elite Gen 6 and Dimensity 9600. In terms of laptops, we can expect to see LPDDR6 paired with some Intel Panther Lake and AMD Medusa Point models.

  • JEDEC Unveils LPDDR6 Standard with 14,400 MT/s Data Rates

    JEDEC Unveils LPDDR6 Standard with 14,400 MT/s Data Rates

    Key Takeaways

    1. Launch of LPDDR6 Standard: JEDEC has introduced JESD209-6, marking the official launch of LPDDR6 five years after DDR5.

    2. Enhanced Performance: LPDDR6 features dual-sub-channel architecture, increasing peak data rates to 10,667 – 14,400 MT/s, providing bandwidths of 28.5 – 38.4 GB/s.

    3. Improved Power Efficiency: The standard reduces power consumption through lower core voltages, Dynamic Voltage Frequency Scaling, and partial self-refresh capabilities.

    4. Increased Reliability: LPDDR6 includes on-die ECC, programmable link protection, and built-in self-test features to enhance fault coverage and reliability for critical applications.

    5. Industry Support and Adoption: Major chipmakers and tech companies, including Qualcomm and Samsung, are backing LPDDR6, indicating rapid adoption across various devices.

    JEDEC has introduced JESD209-6, marking the official launch of LPDDR6, five years after DDR5 made its debut in the market. This new standard enhances peak data rates to between 10,667 and 14,400 MT/s, which translates to bandwidths of about 28.5 to 38.4 GB/s. It also aims to meet the lower power requirements that are critical for mobile devices and next-gen AI technologies.

    Enhanced Performance Features

    The performance improvements stem from a dual-sub-channel architecture. Each memory die includes a 24-bit channel, which is further divided into two 12-bit sub-channels. This setup reduces access times, decreases latency, and keeps a minimum granularity of 32 bytes. Additionally, the capability for on-the-fly burst-length control enables easy transitions between 32 and 64-byte data transfers.

    Better Power Efficiency

    Power efficiency sees enhancements due to lowered core voltages and Dynamic Voltage Frequency Scaling for Low Power, which lowers supply voltages during lighter workloads. The introduction of static and dynamic efficiency settings helps minimize active circuitry when demand is low. Furthermore, the design allows for partial self-refresh to lower standby power usage.

    Improved Reliability Features

    Advancements in reliability come from on-die ECC, programmable link protection, per-row activation counting, and designated meta regions for priority tasks. Additional features like optional command/address parity and built-in self-test capabilities boost fault coverage, fulfilling the more stringent needs of both automotive and data-center applications.

    The industry’s reaction has been immediate. A variety of chipmakers, IP vendors, and suppliers of testing equipment—such as Cadence, Synopsys, MediaTek, Qualcomm, Samsung, Micron, and SK Hynix—have expressed their support, indicating a quick shift towards adoption in smartphones, personal computers, edge servers, and automotive systems.

  • Snapdragon 8 Gen 4 Potential LPDDR6 Support; Apple A18 Pro to Opt for LPDDR5T

    Snapdragon 8 Gen 4 Potential LPDDR6 Support; Apple A18 Pro to Opt for LPDDR5T

    Qualcomm plans to unveil its latest flagship mobile processor, the Snapdragon 8 Gen 4, during the upcoming Snapdragon Summit scheduled for October. As anticipation builds, leaks and speculations surrounding the features and capabilities of the System on Chip (SoC) are emerging.

    Snapdragon 8 Gen 4 Rumors and Features

    A recent report from the South Korean news source Ajunews suggests that the Snapdragon 8 Gen 4 could potentially be among the first mobile SoCs to embrace LPDDR6 memory technology. In comparison, Apple's A18 Pro chipset is rumored to utilize LPDDR5T memory. The report also mentions potential challenges in mass-producing the LPDDR6 module this year, leading to a probable delay in its availability until 2025.

    LPDDR6 Integration and Potential Advantages

    Despite the production hurdles highlighted in the report, there is speculation that Qualcomm might integrate LPDDR6 into its Snapdragon 8 Gen 4 Application Processor (AP) to cater to the increasing demand for on-device AI functionalities. However, it's essential to approach this information with caution until more concrete details emerge. LPDDR6 is anticipated to deliver enhanced speed and power efficiency compared to the current LPDDR5 standard, with the improved performance expected to be especially beneficial for handling AI operations in future smartphones.

    Apple's A18 Pro and Memory Innovations

    While Apple's A18 Pro processor is likely to depend on LPDDR5T memory, there are indications that Apple is exploring alternative methods to store LLMs on NAND flash memory. This potential innovation could enable iPhones with limited RAM to efficiently execute on-device AI tasks. LPDRR5T is currently recognized as the fastest RAM available in smartphone SoCs, boasting theoretical speeds reaching up to 9.6 Gbps.
