3.3V 4M x 64-Bit 2 BANK SDRAM Module
3.3V 4M x 72-Bit 2 BANK SDRAM Module
168 pin unbuffered DIMM Modules

The HYS64(72)V4120GU-10 are industry standard 168-pin 8-byte Dual in-line Memory Modules (DIMMs) which are organised as 4M x 64 and 4M x 72 in two banks high speed memory arrays designed with Synchronous DRAMs (SDRAMs) for non-parity and ECC applications. The DIMMs use 16 2M x 8 SDRAMs for the 4M x 64 organisation and additional two SDRAMs for the 4M x 72 organisation. Decoupling capacitors are mounted on the PC board.
