The most common approach has been so-called “side-band” ECC. With this approach, each memory chip on a DRAM is fully used to store data. Extra chips are added to the DIMM for storing the error codes. This widens the input bus so the data and code can be written at the same time...
The Error Correction Code (ECC) errors are self-correcting. Depending on the Reliability Availability Serviceability (RAS) configuration of the memory, the Integrated Memory Controller (IMC) may take the affected DIMM offline. For different Intel server platforms, there are some differences in their ...
A dual in-line memory module (DIMM) supporting storage of a data indicator(s) in an error correcting code (ECC) storage unit dedicated to storing an ECC. The DIMM is configured to provide a burst ECC storage unit striped in a burst data storage unit. The DIMM is configured to stripe a...

ECC storage. Hence, the DDR4 ECC DIMMs, commonly used in today’s enterprise class servers and data centers, are 72 bits wide. These DIMMs have two additional x4 DRAMs or a single x8 DRAM for the additional 8 bits of ECC storage. Hence, in side-band ECC, the controller writes ...
"correctable memory error rate exceeded for dimm_b1" 是一个硬件错误消息,通常出现在服务器或高端计算机系统中,特别是那些使用 ECC(Error-Correcting Code,错误纠正码)内存的系统。ECC 内存具有检测和纠正内存错误的能力,以提高系统的稳定性和可靠性。然而,当某个内存模块(在这个例子中是 B1 位置的 DIMM,即双列...
This Monday, Linux kernel creator Linus Torvalds went on a frustratedrantabout the lack of Error Correcting Checksum (ECC) RAM in consumer PCs and laptops. ... the misguided and arse-backwards policy of "consumers don't need ECC", [made] the market for ECC memory go away. ...

DRAM(Dynamic Random Access Memory),即动态随机存取存储器,最为常见的系统内存。ECC是“Error Checking and Correcting”的简写,中文名称是“错误检查和纠正”。ECC内存,即应用了能够实现错误检查和纠正技术(ECC)的内存条。EDAC,即Error Detection And Correction(错误检测与纠正)。
