Registered DDR2 SDRAM Modules

Description
The Qimonda HYS72T[128/256]00xHRâ[3S/3.7/5]âA module
family are Registered DIMM modules with 30,0 mm height
based on DDR2 technology. DIMMs are available as ECC
modules in 128M Ã72 (1 GByte) and 256M Ã72 (2 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 Product Types end with a place code, designating the silicon die revision. Example: HYS72T256000HRâ3.7âA, indicating Rev. âAâ 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 âPC2â4200Râ444â11âH0â, where
4200R means Registered DIMM modules with 4.26 GB/sec Module Bandwidth and â444-11â 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
