HYS64V4120GU Siemens, HYS64V4120GU Datasheet - Page 2

• Manufacturer Part Number: HYS64V4120GU
• Description: 3.3V 4M x 64-Bit 2 BANK SDRAM Module 3.3V 4M x 72-Bit 2 BANK SDRAM Module
• Manufacturer: Siemens

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
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“ .
