Product Description
The Micron MT18RTF25672FDY-667G1N8 is a 2 Gigabyte (GB) DDR2 Synchronous Dynamic Random-Access Memory (SDRAM) module. This module is a Fully Buffered DIMM (FB-DIMM), featuring an Advanced Memory Buffer (AMB) chip. The AMB chip serializes data traffic, acting as an intermediary between the memory controller and the DRAM chips. This design was implemented to enhance memory scalability and overcome signal integrity issues inherent in higher densities and speeds of DDR2 memory, making it suitable for server applications. Operating at a speed of 667MHz (PC2-5300), this memory module delivers robust performance for its generation. The 2Rx8 organization indicates that the module comprises two ranks of DRAM chips, with each rank consisting of eight data bits per chip. This configuration is typical for server-grade memory modules. The inclusion of Error-Correcting Code (ECC) is a standard feature for server memory, providing critical data integrity by detecting and correcting memory errors, thus ensuring system reliability. With a CAS Latency (CL) of 5, the MT18RTF25672FDY-667G1N8 offers efficient data access times within the DDR2 standard. It operates at the standard 1.8V voltage. This FB-DIMM is designed for servers and workstations that require DDR2 memory with high density and reliability, supporting demanding computing tasks and ensuring stable operation.
