Memory Expansion Controller Unveiled by Montage Technology
Montage Technology, a leading player in the technology industry, has announced the launch of its latest innovation - the CXL 3.1 Memory eXpander Controller (MXC). This new product is designed to address the growing scalability and bandwidth challenges in standard memory architectures, particularly in the context of the increasing demand for cloud resource pooling.
The CXL 3.1 MXC comes equipped with a dual-channel DDR5 memory controller that can operate at speeds of up to 8000 MT/s. This high-speed memory controller is a significant step forward in enhancing the performance of memory-intensive applications.
The CXL 3.1 MXC, measuring 25 mm x 25 mm, supports both EDSFF (E3.S) and PCIe add-in card (AIC) form factors, providing flexibility in its deployment.
The CXL 3.1 MXC features multiple communication interfaces, including SMBus/I3C, SPI, and JTAG, making it compatible with a wide range of devices. It also supports the CXL.mem and CXL.io protocols, further expanding its compatibility.
Stephen Tai, President at Montage Technology, stated that the CXL 3.1 MXC accelerates the adoption of disaggregated memory architectures, which is a crucial step towards next-generation computing infrastructure.
In addition to Montage Technology, key players such as AMD and Intel are involved in the development and testing of the CXL 3.1 MXC. These companies are testing the product to ensure its compatibility and performance in their respective systems.
The CXL 3.1 MXC is built on a PCIe 6.2 physical layer interface and can achieve data transfer rates of 64 GT/s (x8). It also offers flexible configuration with multi-width and multi-rate support, allowing it to be split via two x4 ports.
Furthermore, the CXL 3.1 MXC includes dual RISC-V microprocessors acting as an Application Processing Unit (APU) and Security Processing Unit (SPU), enhancing its functionality and security.
In summary, the CXL 3.1 MXC is a foundation for memory pooling and sharing in next-generation computing infrastructure. By addressing scalability and bandwidth challenges, it aims to help customers use memory more effectively, contributing to the industry's efforts to adopt disaggregated memory architectures through standards-based solutions.
