General Description

The HB54R1G9F2U is a 128M × 72 × 2 bank Double Data Rate (DDR) SDRAM Module, mounted 36 pieces of 256Mbits DDR SDRAM (HM5425401BTB) sealed in TCP 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.
