混合内存立方（Hybrid Memory Cube, HMC）已被行业领导者和有影响力的人士视为一项万众期待的技术方案，它突破了传统内存技术所受限制，在提供超高系统性能的同时显著减少了每比特耗电量。当代HMC技术提供的带宽是DDR3模块的15倍，而耗电量比该技术降低70%以上，体积减小90%以上。HMC的抽象存储器使设计师可将更多时间投入如何利用HMC的革命性功能和性能上，减少为实现基本功能而选择多个存储器参数所需时间。它还能管理纠错、恢复、刷新和因存储器过程变化而恶化的其他参数。
第二代HMCC规范（HMCC 2.0）定稿于2014年11月19日，是该创新存储器技术开发过程中的一个重要里程碑并预示其后续应用。下载HMC Specification Download 2.0，请访问http://www.hybridmemorycube.org/specification-v2-download-form/。
About Hybrid Memory Cube
Hybrid Memory Cube is a revolutionary innovation in DRAM memory architecture that sets a new standard for memory performance, power consumption and cost.
·HMC Combines high-speed logic process technology with a stack of through-silicon-via （TSV） bonded memory die.
·HMC delivers dramatic improvements in performance, breaking through the memory wall and enabling dramatic performance and bandwidth improvements - a single HMC can provide more than 15x the performance of a DDR3 module.
·The revolutionary architecture of HMC is exponentially more efficient than current memory, utilizing 70% less energy per bit than DDR3 DRAM technologies..
·Hybrid Memory Cube's increased density per bit and reduced form factor contribute to lower total cost of ownership, by allowing more memory into each machine and using nearly 90% less space than today's RDIMMs.
With performance levels that break through the memory wall, Hybrid Memory Cube represents the key to extending network system performance to push through the challenges of new 100G and 400G infrastructure growth. Eventually, HMC will drive exascale CPU system performance growth for next generation HPC systems.
·Whereas DDR4 represents an evolutionary standard, HMC is a revolutionary technology that is a complete paradigm shift from current memory architectures.
·Hybrid Memory Cube will redefine memory. By advancing past the traditional DRAM system, HMC is setting a new standard of memory that can keep up with the advancements of CPUs and GPUs.
·Hybrid Memory Cube could be an absolute game changer for applications ranging from high performance computing to consumer technologies like tablets and graphics cards that value a combination of form factor, energy and bandwidth.
