On June 17th, Marvell Technology Inc. announced the launch of the industry's first 2nm custom SRAM (Static Random Access Memory), a groundbreaking innovation that brings up to 6Gb (768MB) of high-speed on-chip cache to AI xPU compute devices. This custom SRAM demonstrates exceptional performance in multiple aspects, optimizing area and power consumption while achieving a higher operating frequency compared to standard on-chip SRAM. The key features of this custom SRAM are as follows:

● High Capacity and High Speed: It provides up to 6Gb (768MB) of high-speed on-chip cache with a maximum data transfer rate of 6.4Gbit/s.

● Low Power and Small Area: Compared to standard on-chip SRAM, this design saves 15% of chip area, reduces standby power consumption by approximately 66%, and achieves an operating frequency of 3.75GHz.

● Innovative Architecture: It integrates Marvell's advanced custom circuit design, software technology, and 2nm process technology, significantly improving energy efficiency and space utilization.

The Future of AI Infrastructure

Will Chu, Senior Vice President and General Manager of Custom Cloud Solutions at Marvell, emphasized that customization is the future of AI infrastructure. The methodologies and technologies currently used by hyperscale enterprises to develop cutting-edge custom XPUs will gradually permeate to more customers, more device categories, and more applications. Marvell's custom technology platform, leveraging expertise in system and semiconductor design, advanced manufacturing processes, and a comprehensive suite of semiconductor platform solutions and IP, collaborates with customers to create high-performance, high-efficiency infrastructure.

Market Prospects and Industry Impact

With the rapid development of AI technology, the demand for high-performance computing infrastructure continues to grow. Marvell predicts that by 2028, custom chips will account for approximately 25% of the accelerated computing chip market, with a compound annual growth rate of 45%. Marvell's 2nm custom SRAM not only meets this market demand but also offers greater flexibility to chip designers. The freed-up space can be used to integrate more computing cores, expand memory capacity, and reduce device size and cost.

Moreover, Marvell's 2nm custom SRAM is the latest extension of its custom technology platform, which aims to deliver breakthrough results through unique semiconductor design and innovative methods. Previously, Marvell introduced CXL technology for custom silicon chips and custom HBM technology that increases memory capacity by 33%.

Marvell's Platform Strategy

Marvell's technology layout centers around a "building-block platform" approach, integrating key technologies from multiple fields to create a complete ecosystem. Its 2nm platform also features the world's first 3D synchronous bidirectional I/O technology. Compared to traditional unidirectional I/O, this technology doubles the bandwidth or reduces the number of connections by 50%, supporting higher-density 2.5D/3D/3.5D chip stacking. Through deep collaboration with TSMC, Marvell ensures the rapid implementation of advanced process technologies.

Summary

Marvell's launch of the industry's first 2nm custom SRAM represents a significant innovation in the field of AI infrastructure. Its technical advantages in high-speed on-chip cache capacity, area and power consumption optimization, and high operating frequency will bring substantial performance improvements to AI compute devices. Amid the wave of customization, Marvell looks forward to working with partners and customers to create leading technology combinations and drive further development in AI infrastructure.
