Description
The Qimonda HYS72T512020HR–[3.7/5]–A module family
are Registered DIMM modules “RDIMMs” with 50,0 mm
height based on DDR2 technology.
DIMMs are available as ECC modules in 512M x 72
(4 GByte) 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
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 part numbers end with a place code, designating the silicon die revision. Example: HYS72T512020HR–5–A, indicating Rev. “A” 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–444–11–ZZ”, where
4200R means Registered DIMM modules with 4.26 GB/sec Module Bandwidth and “444-11” 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 1.1 and produced
on the Raw Card “ZZ”
