使用CXL进行内存扩展的技术支持计划(TEP)为美光公司提供了一条途径，可以尽早获得技术信息和支持, electrical and thermal models as well as memory products to aid in the design, development and bring-up of next-generation computing platforms.
CXL (Compute Express Link) is a high-speed interconnect, industry-standard interface for communications between processors, accelerators, memory, storage, and other IO devices.
CXL increases efficiency by allowing composability, scalability, and flexibility for heterogeneous and distributed compute architectures. CXL allows applications to share memory among CPU, GPU and FPGA devices which enables sustainability leading to accelerated compute.
该协议用于设备初始化、连接、枚举和设备发现. It is used for devices like FPGAs and IPUs that support CXL.io. Type 1 devices implement a fully coherent cache but no host-managed device memory.
该协议实现了一个可选的一致缓存和主机管理的设备内存. Typical applications are devices that have high-bandwidth memory attached.
This protocol is used only for host-managed device memory. Typical applications are as memory expanders for the host.
The key advantage of CXL is the expansion of the memory for compute nodes, filling the gap for data-intensive applications that require high bandwidth, high capacity and low latency.
Modern compute architectures are prone to the “memory wall” problem. CXL提供了必要的体系结构来平衡计算和内存的伸缩差距. 它创造了一个新的载体，通过内存扩展实现经济可行的内存解决方案, impacting DRAM bit growth rate.
Additionally, CXL灵活且可扩展的体系结构提供了更高的计算和内存资源利用率和操作效率，可以根据工作负载需求扩展或扩展资源.

现代并行计算机体系结构容易出现限制应用程序处理性能的系统瓶颈. Historically, this has been known as the “memory wall”, 微处理器性能的提高速度远远超过DRAM内存速度的提高速度.
用于内存-设备内聚和一致性的CXL协议属性通过支持服务器DIMM插槽之外的内存扩展来解决内存墙问题. CXL内存扩展是一种双管齐下的方法，通过增加带宽来克服内存墙，同时为支持CXL的服务器增加数据密集型工作负载的容量.
CXL附加内存为分层内存存储的新领域提供了巨大的增长机会，并支持独立于CPU内核的内存扩展. CXL will help sustain a higher rate of DRAM bit growth, but don’t expect CXL to cause an acceleration in DRAM bit growth. Overall, it’s a net positive for DRAM growth.

CXL is a cost-effective, flexible, and scalable architectural solution that will shape the data center of the future. 它将改变传统的机架和堆栈架构的服务器和fabric交换机在数据中心的部署方式.
Purpose-built servers that have dedicated fixed resources comprised of CPU, memory, 网络和存储组件将让位于这些更灵活和可扩展的架构. Servers in the rack – once interconnected to fixed resources for network, 存储和计算——将动态组合，以满足人工智能和深度学习等现代和新兴工作负载的需求. Eventually, 数据中心将迁移到所有服务器元素的完全分解, including compute, memory, network, and storage.
