1.0 Description

The INFINEON HYS72T32000GR, HYS72T64020GR and HYS72T64001 are low profile

Registered DIMM modules with 30,00 mm height based on DDR2 technology. DIMMs are available

in 32M x 72 (256 MByte), 2 x 32M x 72 (512 MByte) and 64M x 72 (512 MByte) organisation and

density, intended for mounting into 240 pin connector sockets.

The memory array is designed with 256Mbit Double Data Rate (DDR2) Synchronous DRAMs for

ECC applications. All control and address signals are re-driven on the DIMM using register devices

and a PLL for the clock distribution. This reduces capacitive loading to the system bus, but adds one

cycle to the SDRAM timing. Decoupling capacitors are mounted on the PCB board, which provide

a proper voltage supply impedance over the whole frequency range of operations as number and

values are accordant to the JEDEC specification. The DIMMs feature serial presence detect based

on a serial E2PROM device using the 2-pin I2C protocol. The first 128 bytes are programmed with

configuration data and the second 128 bytes are available to the customer.
