Description
The
Qimonda
HYS72T256300EP–[25F/2.5/3/3S/3.7]–C
module family are Very Low Profile Registered DIMM
modules “VLP RDIMMs” with parity bit for address and control
bus and 18.30 mm height based on DDR2 technology.
DIMMs are available as ECC modules in 256M
× 72 (2GB) in
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 are
write protected; the second 128 bytes are available to the
customer.

Product Type1)
1) For detailed information regarding Product Type of Qimonda please see chapter "Product Type Nomenclature" of this datasheet.
Compliance Code2)
2) The Compliance Code is printed on the module label and describes the speed grade, for example "PC2–6400P–555–12–ZZ" where 6400P
means Registered DIMM with Parity bit modules with 6.40 GB/sec Module Bandwidth and "555–12" means Column Address Strobe (CAS)
latency =5, Row Column Delay (RCD) latency = 5 and Row Precharge (RP) latency = 5 using the latest JEDEC SPD Revision 1.2 and
produced on the Raw Card "Z".
