4M × 32-Bit Dynamic RAM Module SMALL OUTLINE MEMORY MODULE
The HYM 324000GD -50/-60 is a 16 MByte DRAM module organized as 4 194 304 words by 32-bit in a 72-pin, dual read-out, small outline package comprising two HYB 3165160T 4M × 16 DRAMs in 500 mil wide TSOPII-54 - packages mounted together with two 0.2 µF ceramic decoupling capacitors on a PC board. Each HYB 3165160T 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.
