Description
The HYS72D[128/64/32]5[00/20/21]GR–[7F/7/8]-B are low profile versions of the standard Registered DIMM
modules with 1.2” inch (30,48 mm) height for 1U Server Applications. The Low Profile DIMM versions are available
as 32M

72 (1 GB).
The memory array is designed with Double Data Rate 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. A variety of decoupling capacitors
are mounted on the PC board. The DIMMs feature serial presence detect based on a serial E

PROM device using
the 2-pin I

C protocol. The first 128 bytes are programmed with configuration data and the second 128 bytes are
available to the customer.
