3.3V 4M × 64-Bit EDO-DRAM Module 3.3V 4M x 72-Bit EDO-DRAM Module 168pin unbuffered DIMM Module with serial presence detect The HYM64(72)V4005/45GU-50/-60 are industry standard 168-pin 8-byte Dual In-Line Memory Modules (DIMMs) which are organized as 4M x 64 and 4M x 72 high speed memory arrays designed with EDO DRAMs for non-parity and ECC applications. 2k refresh with 11 / 11 addressing and 4k refresh modules with 12 / 10 addressing are available. The DIMMs use sixteen 4M x 4 EDO DRAMs for the 4M x 64 organisation and eighteen 4M x 4 DRAMs for the 4M x 72 organisation, both in TSOPII packages. Decoupling capacitors are mounted on the PC board. • 168 Pin JEDEC Standard, Unbuffered 8 Byte Dual In-Line Memory Module for PC main memory applications • 1 bank 4M x 64, 4M x 72 in 2k and 4k refresh organisations • Optimized for byte-write non-parity or ECC applications • Extended Data Out (EDO) • Performance: • Single +3.3 V ± 0.3 V Power Supply • CAS-before-RAS refresh, RAS-only-refresh • Decoupling capacitors mounted on substrate • All inputs, outputs and clocks are fully LV-TTL compatible • Serial presence detects (optional) • Utilizes 4M x 4 -DRAMs in TSOPII packages • 2048 refresh cycles / 32 ms with 11 / 11 addressing ( Row / Column) for HYM64/72V4005GU • 4096 refresh cycles / 64 ms with 12 / 10 addressing ( Row / Column) for HYM64/72V4045GU • Gold contact pads • Card Size: 133,35mm x 25,40 mm x 4,00 mm • This DRAM product module family is intended to be fully pin and architecture compatible with the 168pin unbuffered SDRAM DIMM module family
