Each HYB 3165800T 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. These modules are ideal for portable systems applications where high memory capacity is needed.
