HYS72T256000ER-[3.7/5]-B
Registerd DDR2 SDRAM Module
1.2
Description
The QIMONDA HYS72T256000ER-[3.7/5]-B module family
are Registered DIMM modules “RDIMMs” with 30 mm height
based on DDR2 technology. DIMMs are available ECC
modules in 256M
×
72 (2 GB) organization and density,
intended for mounting into 240-pin connector sockets.
The memory array is designed with 1-Gbit Double-Data-Rate-
Two (DDR2) Synchronous DRAMs.
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.
Decoupling capacitors
are mounted on the PCB board. The DIMMs feature serial
presence detect based on a serial E
2
PROM device using the
2-pin I
2
C protocol. The first 128 bytes are programmed with
configuration data and are write protected; the second
128 bytes are available to the customer.

1) All Product Type numbers end with a place code, designating the silicon die revision. Example: HYS72T256000ER–3.7–B, indicating Rev.
“B” dies are used for DDR2 SDRAM components. For all Qimonda DDR2 module and component nomenclature see
Chapter 6
of this data
sheet.
2) The Compliance Code is printed on the module label and describes the speed grade, for example “PC2–4200R–444–12–H0”, where
4200R means Unbuffered DIMM modules with 4.26 GB/sec Module Bandwidth and “444-12” means Column Address Strobe (CAS)
latency = 4, Row Column Delay (RCD) latency = 4 and Row Precharge (RP) latency = 4 using the latest JEDEC SPD Revision 1.2 and
produced on the Raw Card “H”.
