The HYS72D[32/64/128]3[00/20]GBR are low profile versions of the standard Registered DIMM modules with
less/equal 1.2” inch (30.48 mm) height for 1U Server Applications. The Low Profile DIMM versions are available
as 32M
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
the 2-pin I
available to the customer.
