Samsung announces the industry’s first LPDDR5X
Samsung announced the launch of the industry’s first 14nm process, 16Gbit LPDDR5X, aimed at promoting the further growth of memory, covering various applications that rely on high-speed data services including 5G, AI, and AR. Samsung said that in addition to smartphones, LPDDR5X also expands the use of high-performance, low-power memory, which can bring new functions to AI-based edge applications such as servers or cars.
The memory speed of this LPDDR5X is 8.5 Gbps, which is 1.3 times that of the current LPDDR5 (6.4 Gbps). After using the 14nm process, the power consumption is also reduced by about 20% compared to LPDDR5. The single-chip capacity of 16Gbit, maximum packaging capacity of 64GB, to meet the higher capacity needs of the mobile field. Samsung has already started mass production of DDR5 DRAM using the 14nm process of EUV (Extreme Ultraviolet) technology, and perhaps LPDDR5X will also use it.
In July of this year, the JEDEC Solid State Storage Association officially announced the JESD209-5B standard, the LPDDR5X standard, which was developed by the JC-42.6 Low Power Memory Subcommittee of JEDEC. Samsung also participated in related work. This is an optional extension to LPDDR5, focusing on improving performance, power consumption, and flexibility, and aims to improve memory performance in application scenarios including 5G communication performance, automotive high-resolution augmented reality/virtual reality, and edge computing using AI.
Compared with the previous LPDDR5, the improved LPDDR5X has been updated in many aspects, including the transmission rate increased to 8533MT/s; improve signal integrity through TX/RX equalization; improve reliability with new adaptive refresh management, as an optional extension, it aims to provide higher bandwidth and simplified architecture.
