2 / 11 page Semiconductor Group 2 HYM72V4000/10GS-50/-60 4M x 72-ECC Module The HYM 72V4000/10GS-50/-60 is a 32 MByte DRAM module organized as 4 194 430 words by 72- bit in a 168-pin, dual read-out, single-in-line package comprising eighteen HYB 3116400BT/BJ 4M × 4 DRAMs in 300 mil wide TSOPII or SOJ- 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. Each HYB 3116400BT/BJ 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 module can be detected by the use of presence detect pins. Ordering Information Pin Names Presence-Detect and ID-pin Truth Table: Note: 1 = High Level ( Driver Output) , 0 = Low Level (Driver Output) for PDE active ( ground) . For PDE at a high level all PD terminal are in tri-state.
