HYM322000S

The HYM HYM322000S is a 8 MByte DRAM module organized as 2 097 152 words by 32-bit in a 72-pin single-in-line package comprising four HYB 5118160BSJ 1M ´ 16 DRAMs in 400 mil wide SOJ-packages mounted together with four 0.2 mF ceramic decoupling capacitors on a PC board.

The HYM HYM322000S can also be used as a 4 194 304 words by 16-bits dynamic RAM module by means of connecting DQ0 and DQ16, DQ1 and DQ17, DQ2 and DQ18, ., DQ15 and DQ31,respectively.

Each HYB HYM322000S 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 speed of the HYM322000S module can be detected by the use of four presence detect pins.

The common I/O feature on the HYM 322000S/GS-50/-60/-70 dictates the use of early write cycles.
