3.3V 4M x 64/72-Bit 1 BANK SDRAM Module
3.3V 8M x 64/72-Bit 2 BANK SDRAM Module
PC66 & PC100 168 pin unbuffered DIMM Modules

The HYS64(72)V4200 and HYB64(72)V8220 are an industry standard 168-pin 8-byte Dual in-line Memory Module (DIMM) which are organised as 4M x 64, 4M x 72 in an one bank and 8M x 64, 8M x72 in two banks high speed memory arrays designed with 64Mbit Synchronous DRAMs (SDRAMs Die Rev.B) for non-parity and ECC application. The DIMMs use -8 and -8B speed sort 4M x 16 SDRAM devices in TSOP54 packages to meet the PC100 requirements and -10 parts for 66 MHz bus speed applications. Decoupling capacitors are mounted on the PC board. The PC board design is according to INTEL’s module specification.
