MediaTek has validated Micron Technology's low-power double data rate 5X (LPDDR5X) DRAM for MediaTek's new Dimensity 9000 flagship chipset for 5G smartphones, according to Micron.

Micron claimed it is the first semiconductor company to sample and validate this fastest, most advanced mobile memory in the industry. Micron has shipped the first batch of samples of LPDDR5X built on its 1α (1-alpha) node. Designed for high-end and flagship smartphones, Micron's LPDDR5X allows the smartphone ecosystem to unlock the next wave of data-intensive applications powered by AI and 5G innovation, it added.

The market delivery and validation of Micron's 1α-based LPDDR5X solidifies its product innovation and leadership in the mobile ecosystem, following industry-first launches for LPDDR5, 1α-based LPDDR4X, 176-layer NAND-based UFS 3.1 and uMCP5 solutions, it noted. This most recent milestone follows quickly on the heels of JEDEC's July release of the LPDDR5X extension to LPDDR5. Micron has validated samples supporting data rates up to 7.5 Gb/s, with samples supporting data rates up to 8.533 Gb/s to follow. Peak LPDDR5X speeds of 8.533 Gb/s deliver up to 33% faster performance than previous-generation LPDDR5.

These new levels of memory performance are increasingly critical for feeding massive amounts of data to the multiple heterogeneous processing engines built into today's complex smartphone SoCs, Micron indicated. As mobile workloads grow more sophisticated, these advanced SoCs rely on high data rates to ensure seamless multitasking across applications and to enable AI inferencing, augmented and virtual reality, and immersive graphics.

Micron said it is collaborating with the world's leading smartphone manufacturers and chipset vendors to enable ecosystem innovation with LPDDR5X. As part of this effort, MediaTek's Dimensity 9000 mobile SoC will be the first to support LPDDR5X memory, delivering industry-leading peak bandwidth of 60 gigabytes per second for high-end and flagship smartphones, it said.
