SDRAM-Modules
The HYS64(72)2200 and HYS64(72)4220 are industry standard 168-pin 8-byte Dual in-line Memory Modules
(DIMMs) which are organised as 2M x 64, 2M x 72 in 1 bank and 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 -8 speed sort 2M x 8 SDRAM devices in TSOP44 packages to meet the PC100 requirement. Modules which
use -10 parts are suitable for PC66 applications only. Decoupling capacitors are mounted on the PC board. The
PC board design is according to INTEL’s PC SDRAM Rev.1.0 module specification.

The DIMMs have a serial presence detect, implemented with a serial E
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,
with 1,25“ ( 31,75 mm) height
