Description
The HYS72D[128/256][300/320/321/500][GBR/HR]-[5/6/7/7F]-B are low profile versions of the standard
Registered DIMM modules with 1.1” inch (28.58) and 1.2” inch (30,40 mm) height for 1U Server Applications. The
Low Profile DIMM versions are available as 128M × 72 (1 GB) and 256M × 72 (2 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.
