Description
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 × 72 (256MB), 64M × 72 (512MB) and 128M × 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 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.
