HYS64(72)V4120GU-10
4M x 64/72 SDRAM-Module
The HYS64(72)V4120GU-10 are industry standard 168-pin 8-byte Dual in-line Memory Modules
(DIMMs) which are organised as 4M x 64 and 4M x 72 in two banks high speed memory arrays
designed with Synchronous DRAMs (SDRAMs) for non-parity and ECC applications. The DIMMs
use 16 2M x 8 SDRAMs for the 4M x 64 organisation and additional two SDRAMs for the 4M x 72
organisation. Decoupling capacitors are mounted on the PC board.
The DIMMs have a serial presence detect, implemented with a serial E
2
PROM using the two pin I
2
C
protocol. The first 128 bytes are utilized by the DIMM manufacturer and the second 128 bytes are
available to the end user.
All SIEMENS 168-pin DIMMs provide a high performance, flexible 8-byte interface in a 133,35 mm
long footprint. This SDRAM module is available with a board-height of 1,15“
.
