DATA SHEET 512MB Registered DDR SDRAM DIMM HB54A5129F1U-A75B/B75B/10B (64M words × 72 bits, 1 Bank) Description The HB54A5129F1U is a 64M × 72 × 1 bank Double Data Rate (DDR) SDRAM Module, mounted 18 pieces of 256Mbits DDR SDRAM (HM5425401BTT) sealed in TSOP package, 1 piece of PLL clock driver, 2 pieces of register driver and 1 piece of serial EEPROM (2k bits EEPROM) for Presence Detect (PD). Read and write operations are performed at the cross points of the CK and the /CK. This high-speed data transfer is realized by the 2-bit prefetch-pipelined architecture. Data strobe (DQS) both for read and write are available for high speed and reliable data bus design. By setting extended mode register, the on-chip Delay Locked Loop (DLL) can be set enable or disable.
