DDR4 LRDIMM
M88DR4DB02P/M88NR4DB02P (Gen2 Plus DDR4 DB)
M88DR4DB02P/M88NR4DB02P is a Gen2 Plus DDR4 Data Buffer (DB), which is compliant with the JEDEC DDR4DB02 specification and supports data rates up to DDR4-3200. The DBs can be used in conjunction with Montage’s Gen2 Plus DDR4 RCD (M88DR4RCD02P) for LRDIMM and NVDIMM (Non-Volatile Dual In-line Memory Module) applications, that is, 1 * RCD + 9 * M88DR4DB02P used for one LRDIMM, or 1 * RCD + 9 * M88NR4DB02P used for one NVDIMM.
The left image shows the application of DB on the DDR4 LRDIMM as an example.
