HYM64V8045GU-50中文资料西门子数据手册PDF规格书

The HYM64(72)V2005/45GU-50/-60 are industry standard 168-pin 8-byte Dual In-Line Memory Modules (DIMMs) which are organized as 8M x 64 and 8M x 72 high speed memory arrays designed with EDO DRAMs for non-parity and ECC applications. 4k refresh with 12 / 11 addressing and 8k refresh modules with 13 / 10 addressing are available.The DIMMs use eight 8M x 8 EDO DRAMs for the 8M x 64 organisation and nine 8M x 8 DRAMs for the 8M x 72 organisation, both in TSOPII packages. Decoupling capacitors are mounted on the PC board.
