Description
The
Qimonda
HYS72T[64/128/256]xx0EP–
[2.5/25F/3/3S/3.7]–B2 module family are Registered DIMM
modules “RDIMMs” with parity bit for address and control bus
and 30 mm height based on DDR2 technology. DIMMs are
available
as
ECC
modules
in
128M
× 72 (1GB),
256M
× 72 (2GB), 64M × 72 (512MB) in organization and
density, intended for mounting into 240-pin connector
sockets.
The memory array is designed with 512MBit 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
2PROM 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.
