Silicon Motion introduces the SM2504XT ES 2TB SSD controller as a competitor in the mid-grade PCIe 5.0 segment, offering high performance, 10+ GB/s transfers, and power efficiency. The controller supports up to 11,500 / 11,000 MB/s for sequential reads and writes and up to 1,700K / 2,000K random read and write IOPS, putting it on par with the Phison E31T controller. The SM2504XT ES is a DRAM-less solution suitable for laptops, mobile devices, and small-form-factor desktops, offering a balance of performance and power efficiency. The controller's triple-core Arm Cortex-R8 processor enables up to 2 million IOPS, showcasing significant power for a mid-range drive.
SK hynix has completed the development of HBM4 memory, surpassing the 8Gbps specification with speeds of 10Gbps per pin. The company is now prepared for mass production of this high-performance memory technology.
Researchers from SUSTech and Shanghai Jiao Tong University have created a DNA cassette tape drive that combines DNA storage with a physical tape-based medium, aiming for petabytes-per-meter density and multi-century lifespan. The system currently writes at kilobytes per hour, with a capacity of over half a terabyte per kilometer. While the prototype shows promise in durability and potential data storage, the slow read-write speeds hinder practical application. The DNA tape is encased in a protective shell for longevity, with estimated shelf life of over 300 years at room temperature. Despite challenges in scaling for commercial use, the project highlights the need for new data storage solutions beyond semiconductor-based memory.
The article discusses the evolution of memory technology, highlighting LPDDR as a key solution for mobile, edge, and endpoint platforms due to its balance of performance and power efficiency. LPDDR has advanced through generations, with LPDDR6 offering features like dual sub-channels and enhanced reliability for AI inference workloads. Compared to HBM and GDDR, LPDDR excels in energy efficiency and idle power savings, making it ideal for devices where battery life and thermal limits are crucial. LPDDR is increasingly integrated into smartphones, tablets, laptops, automotive systems, and AI accelerators, offering unique features like fine-grained concurrency and reliability enhancements. The article emphasizes the importance of LPDDR in the evolving landscape of mobile, automotive, and edge AI platforms.
