The 4DB0232KD is a JEDEC compliant DDR4 Data Buffer with dual 4-bit bidirectional “DQ” data registers and “DQS” differential strobes. It is designed for 1.2 VDD operation in DDR4 LRDIMM applications. The DQ host interface side of each 4-bit bidirectional data register is connected to a memory controller while the MDQ interface side is connected to two x4 DRAMs. The 4DB0232KD supports speeds up to 3200 just like the 4DB0232KC, but also has improved power efficiency.
