微米's DDR5 Technology Enablement Program Empowers an Ecosystem

我们美光经常感觉自己是科技行业向下一代计算的重大革命迈进的先锋. 从当今世界产生的大量数据中提取价值和见解, that revolution will take advanced 内存, along with additional compute power.

今天的系统架构师知道，DDR4 SDRAM已经达到了3200 MT/s的瓶颈，而CPU核数还在继续增加. So, 计算性能的持续提升需要高性能内存来维持每个CPU核心的可用带宽. 添加带有DDR4的内核实际上会导致每个CPU内核的带宽下降.

JEDEC announced the standard for fifth-generation double data rate (DDR5) SDRAM 将于2020年7月推出，以满足对更高带宽的需求，并对前几代SDRAM进行大规模改进. DDR5 is the most technologically advanced DRAM to date, 启用 the next generation of server workloads by delivering more than an 85% increase in 内存 performance at the introduction data rate of 4800 MT/s. 与DDR4相比，DDR5将继续实现两倍以上的数据速率和有效带宽, 为实现年复一年的计算增益所需的CPU核心数量的增加提供了动力.

Opportunities and concerns arise with a new 内存 technology

随着新特性和功能的引入，内存技术的重大转变可能会给采用者和开发人员带来许多问题和挑战. How will 热s compare? How can a designer get access to functional models for simulation? What are key technical differences to consider? Because DDR5 is such a different animal from DDR4, 架构师和设计师发现他们必须从不同的角度考虑DDR5的采用, 或者提出.

Here are some examples:

• 为了提高效率和稳定性，DDR5模块引入了电源管理集成电路(PMIC)的本地电压调节。, which has historically been done on the motherboard.
• DDR5模块在每个DIMM中引入两个40位独立通道，支持突发长度16, 而DDR4每个DIMM只使用一个72位通道，突发长度为8.
• DDR5模块引入了一个注册时钟驱动程序(RCD)，它为DIMM上的每个独立通道提供单独的时钟和地址资源.
• DDR5引入了决策反馈均衡(DFE)来减轻高数据速率下符号间干扰(ISI)的影响.
• DDR5包括改进的刷新方案(同一银行刷新)，通过针对每个银行集团的一家银行来帮助进一步提高性能.

DDR5 TEP鼓励发现和开发下一代沙巴体育结算平台

Hyperscalers, large server companies, and PC OEMs are already integrating DDR5, so it’s expected that workloads using DDR4 now will migrate to DDR5. But these new systems don’t just appear overnight. DDR5 内存 holds great promise; that’s why 微米 created the TEP — to enable partners to draw on ecosystem collaboration to streamline design and integration challenges.

What’s also interesting to me is how, as the DDR5 technology matures and TEP membership expands, TEP的需求正在发生变化，我们正在提供新的信息. In this transition to DDR5 内存, TEP的成员可能会发现他们自己的兴趣和记忆也需要发展.

微米’s unique ecosystem for DDR5 collaboration grows rapidly

微米 was one of the first to sample DDR5 with data center customers, but we saw there was a deeper need. “As a lead developer of DDR5 specifications, 微米 saw the opportunity early in DDR5 standards 发展,” said 微米’s CEO, Sanjay Mehrotra. “这就是为什么我们启动了DDR5技术支持计划(TEP)，以帮助整个生态系统为DDR5平台集成和优化做好准备.”

的 微米 DDR5 TEP, announced a year ago with a handful of ecosystem partners that included Cadence, 蒙太奇, Rambus, Renesas and Synopsys, is the first and only one of its kind in the industry. It has now grown to over 250 members from more than 100 companies. Many leaders in areas such as ecosystem and IP enablement, system integration, system architecture, CPU和ASIC设计已经加入，并正在努力确保顺利过渡到DDR5.

我们为生态系统积极支持美光DDR5 TEP“一站式服务”的方式感到自豪，所有关键技术内容都在开发人员和采用者的指尖. 微米 is providing early access to technical information, 支持, and electrical and 热 models. 不仅如此, 但美光也通过这个项目播种了DDR5样品沙巴体育结算平台，以帮助工业设计, 发展, and growth of computing platforms.

的 TEP is a one-stop shop for DDR5 design and documents

美光坚定地致力于系统内存这一重要飞跃的成功. 我们已经使找到将DDR5集成到合作伙伴的系统和平台中的材料变得容易和容易. Once membership in the program is approved, members receive:

• Technical resources such as data sheets, 热, 和功能仿真模型，以帮助沙巴体育结算平台开发和平台建设
• Select DDR5 component and module samples as they become available
• 与其他生态系统合作伙伴建立联系，帮助设计和推出支持DDR5的平台
• Technical 支持 and training materials

Given the enthusiastic reception of DDR5 DRAM standards, 认识到这种高性能的新存储器将是多么重要和潜在的破坏性, and the amazing growth of the 微米 DDR5 TEP ecosystem, I predict great things are in store. Capture your own spot in the upcoming revolution!
