理解CUDIMM：提升DDR5内存时钟信号完整性Understanding CUDIMM: Enhancing Clock Signal Integrity in DDR5 Memory
➀ CUDIMM，即Clocked Unbuffered DIMM，通过引入时钟驱动器（CKD）来提高高频DDR5内存模块的信号完整性。 ➁ CKD将时钟域分为连接CPU的DCK和连接设备的QCK，类似于RDIMM中的RCD，但更为简化。 ➂ 对于笔记本内存模块（SODIMM），采用类似的方法，即CSODIMM，也包含CKD以增强时钟信号管理。 ➃ JEDEC推荐在PC5-6400以上的UDIMM模块使用CUDIMM，并且CKD解决方案可从多家制造商获得，包括中国的澜起。➀ CUDIMM, or Clocked Unbuffered DIMM, is designed to improve signal integrity in high-frequency DDR5 memory modules by introducing a Clock Driver (CKD). ➁ The CKD splits the clock domain into DCK (connected to the CPU) and QCK (connected to devices), similar to the RCD in RDIMM but simplified. ➂ For laptop memory modules (SODIMM), a similar approach is taken with CSODIMM, which also incorporates a CKD for enhanced clock signal management. ➃ JEDEC recommends CUDIMM for UDIMM modules above PC5-6400, and CKD solutions are available from various manufacturers, including Lanqi in China.
