3.3V 2M x 64/72-Bit 1 BANK SDRAM Module
3.3V 4M x 64/72-Bit 2 BANK SDRAM Module
168 pin unbuffered DIMM 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.
