Samsung LPDDR5X – 128GB – x64 Mobile DRAM

Samsung LPDDR5X 128GB (x64 organization) is designed for ultra-high density mobile and embedded platforms that require extreme bandwidth with optimized power efficiency. Built on advanced process technology, this LPDDR5X solution supports data rates up to 8.5Gbps while maintaining lower operating voltage compared with previous LPDDR generations.

The x64 configuration enables wider data paths and improved parallel processing capability, making it suitable for high-performance mobile SoCs, AI edge processors, and automotive compute platforms.

Performance Architecture

• Maximum data rate up to 8.5Gbps per pin
• x64 organization for high bandwidth applications
• Improved signal integrity at high frequency
• Enhanced prefetch and burst efficiency
• Optimized routing for advanced mobile PCB layouts

Compared with LPDDR4X, LPDDR5X increases effective memory bandwidth while reducing latency sensitivity under heavy workloads. This makes it a suitable solution for LPDDR5X 128GB mobile memory chip integration in next-generation flagship devices.

Power Efficiency & DVFS Support

Integrated Dynamic Voltage and Frequency Scaling (DVFS) allows adaptive performance scaling based on workload demand. Power consumption is reduced by approximately 20% versus LPDDR4X while maintaining higher transfer speeds.

• Lower standby and active power
• Reduced thermal output under sustained load
• Improved battery runtime in mobile platforms
