The HYS 64V64220GU and HYS 72V64220GU are industry standard 168-pin 8-byte Dual in-line
Memory Modules (DIMMs) which are organized as 64M
脳
64 and 64M
脳
72 in two banks high speed
memory arrays designed with 256M Synchronous DRAMs (SDRAMs) for non-parity and ECC
applications. The DIMMs use 7-5 speed sorted 256 Mbit Synchronous DRAMs (SDRAMs) to meet
the PC133-333 requirements and -8, -8A and -8B components for the standard PC100 applications.
Decoupling capacitors are mounted on the PC board. The PC board design is according to INTEL鈥檚
PC100 module specification. The DIMMs have a serial presence detect, implemented with a serial
E
2
PROM using the 2-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 Infineon 168-pin DIMMs provide a high
performance, flexible 8-byte interface in a 133.35 mm long footprint, with 1.25鈥?(31.75 mm) height.
