The HYS 72Vxx5/6x0GR-7.5 are industry standard 168-pin 8-byte Dual in-line Memory Modules (DIMMs)
organized as 16M
72, 32M x 72, 64M
72 and 128M x 72 high speed memory arrays designed with x4 or x8
organised Synchronous DRAMs (SDRAMs) for ECC applications. All control and address signals are registered
on-DIMM and the design incorporates a PLL circuit for the Clock inputs. Use of an on-board register reduces
capacitive loading on the input signals but are delayed by one cycle in arriving at the SDRAM devices. Decoupling
capacitors are mounted on the PC board. The DIMMs use a serial presence detects scheme implemented via a
serial E
2
PROM using the 2-pin I
2
C protocol. The first 128 bytes are utilized by the DIMM manufacturer and the
second 128 bytes are available to the end user. All Infineon 168-pin DIMMs provide a high performance, flexible
8-byte interface in a 133.35 mm long footprint. This module family is designed with 30,40 mm (1.2 inch) maximum
height for 1U Server Applications b ased on JEDEC standard RawCards 鈥淔鈥?and 鈥淕鈥?
