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.
