HYM641020GS-70

The HYM HYM641020GS-70 is a 8 MByte DRAM module organized as 1 048 576 words by 64- bit in a 168-pin, dual read-out, single-in-line package comprising sixteen HYB 514400BJ/BT 1M x 4 DRAMs in 300 mil wide SOJ or TSOPII - packages mounted together with sixteen 0.2 F ceramic decoupling capacitors on a PC board. All inputs except RAS and DQ are buffered by using four BiCMOS 8-bit buffers/line drivers.

Each HYB 514400BJ/BT is described in the data sheet and is fully electrically tested and processed according to Siemens standard quality procedure prior to module assembly. After assembly onto the board, a further set of electrical tests is performed.

The density and speed of the HYM641020GS-70 module can be detected by the use of presence detect pins.
