8M × 72-Bit Dynamic RAM Module (ECC - Module)

168 pin buffered DIMM Module

The HYM 72V8020/30GS-50/-60 is a 64 MByte DRAM module organized as 8 388 608 words by 72- bit in a 168-pin, dual read-out, single-in-line package comprising nine HYB3165800AJ/AT 8M × 8 DRAMs in 400 mil wide SOJ or TSOPII - packages mounted together with ceramic decoupling capacitors on a PC board. All inputs except RAS and DQ are buffered by using BiCMOS buffers/ line drivers.
