The HYM a 16 MByte DRAM module organized 194 304 words a 72-pin single-in-line package comprising eight HYB x 4 DRAMs in 300 mil wide SOJ-packages mounted together with eight 0.2 F ceramic decoupling capacitors a PC board. Each HYB 5117405BJ is described in the data sheet and is fully electrical 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 speed of the module can be detected by the use of four presence detect pins. The common I/O feature on the HYM 324025S/GS-50/-60 dictates the use of early write cycles.
