HYS[64/72]T256020EU-[25F/2.5/3/3S/3.7]-B
Unbuffered DDR2 SDRAM Module
1.2
Description
The QIMONDA HYS[64/72]T256020EU-[25F/2.5/3/3S/3.7]-B
module family are unbuffered DIMM modules âUDIMMsâ with
30 mm height based on DDR2 technology. DIMMs are
available as non-ECC modules in 256M Ã 64 (2 GB) and as
ECC modules in 256M Ã 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. 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 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: HYS72T256020EUâ3.7âB, indicating Rev.
âBâ 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 âPC2â4200Uâ444â12âE0â, where
4200U means Unbuffered DIMM modules with 4.26 GB/sec Module Bandwidth and â444-12â 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 âBâ.
