HYM361140S-70

The HYM HYM361140S-70 is a 4 MByte DRAM module organized as 1 048 576 words by 36-bit in a 72-pin single-in-line package comprising four HYB 511000BJ 1M x 1 DRAMs and eight HYB 514400BJ 1M ´ 4 DRAMs in 300 mil wide SOJ-packages mounted together with twelve 0.2 mF ceramic decoupling capacitors on a PC board.

The HYM HYM361140S-70 can also be used as a 2 097 152 words by 18-bits dynamic RAM module by means of connecting DQ0 and DQ18, DQ1 and DQ19, DQ2 and DQ20, ., DQ17 and DQ35, respectively.

Each HYB 511000BJ and HYB 514400BJ 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 module can be detected by the use of four presence detect pins.|

The common I/O feature on the HYM361140S-70 dictates the use of early write cycles.
