3.3 V 8M × 64/72-Bit 1 Bank SDRAM Module
3.3 V 16M × 64/72-Bit 2 Bank SDRAM Module
168 pin unbuffered DIMM Modules

The HYS 64(72)8200 and HYS 64(72)16220 are industry standard 168-pin 8-byte Dual in-line Memory Modules (DIMMs) which are organized as 8M × 64, 8M × 72 in 1 bank and 16M × 64 and 16M × 72 in two banks high speed memory arrays designed with 64M Synchronous DRAMs (SDRAMs) for non-parity and ECC applications. The DIMMs use -8 and -8B speed sort 8M 8 SDRAM devices in TSOP-54 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.
