The HYM 72V1600/10GS-50/-60 is a 128 MByte DRAM module organized as 16 777 216 words by 72-bit in a 168-pin, dual read-out, single-in-line package comprising eighteen HYB 3164400BT/BJ 16M × 4 DRAMs in 500 mil wide TSOPII or SOJ- packages mounted together with eighteen 0.2 μF ceramic decoupling capacitors on a PC board. All inputs except RAS and DQ are buffered by using four BiCMOS 8-bit buffers/line drivers.
