Description
The HYS72D[128/64/32][300/320]GBR–[5/6]–C and HYS72D64320GBR–5–C are low profile versions of the
standard Registered DIMM modules suitable for 1U Server Applications. The Low Profile DIMM versions are
available as 32 M ×72 (256 MB), 64 M ×72 (512 MB) and 128 M ×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.
