HYS72D[64/128/256]xxx[G/H]BR–[5/6/7]–B
Registered DDR SDRAM Module
1.2
Description
The HYS72D[64/128/256]xxx[G/H]BR–[5/6/7]–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
64M × 72(512 MB), 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 de coupling 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.

1) All product types end with a place code designating the silicon-die revision. Reference information available on request.
Example: HYS72D128300GBR-5-B, indicating Rev.B die are used for SDRAM components.
2) The Compliance Code is printed on the module labels and describes the speed sort (for example “PC2100R”), the latencies (for example
“20330” means CAS latency of 2.0 clocks, Row-Column-Delay (RCD) latency of 3 clocks and Row Pre-charge latency of 3 clocks), JEDEC
SPD code definition version 0, and the Raw Card used for this module.
