The HYM 362140S/GS-60/-70 can also be used as a 4 194 304 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 electrical 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 HYM 362140S/GS-60/-70 dictates the use of early write cycles.

Specified values are measured with the output open. 4) An initial pause of 200 µs is required after power-up followed by 8 RAS cycles out of which at least one cycle has to be a refresh cycle before proper device operation is achieved. In case of using internal refresh counter, a minimum of 8 CAS-before-RAS initialization cycles instead of 8 RAS cycles are required. 5) VIH (max) and VIL (max) are reference levels for measuring timing of input signals. Transition times are also measured between VIH and VIL. 6) Measured with a load equivalent of 2 TTL loads and 100 pF. 7) tOFF (max) defines the time at which the output achieves the open-circuit condition and is not referenced to output voltage levels. 8) Either tRCH or tRRH must be satisfied for a read cycle. 9) These parameters are referenced to the CAS leading edge. 10) tWCS is not a restrictive operating parameter. This is included in the data sheet as electrical characteristic only. If tWCS > tWCS (min), the cycle is an early write cycle and data out pin will remain open (high impedance). 11) Operation within the tRCD (max) limit insures that tRAC (max) can be met. tRCD (max) is specified as a reference point only. If tRCD is greater than the specified tRCD (max) limit, then access time is controlled by tCAS. 12) Operation within the tRAD (max) limit insures that tRAC (max) can be met. tRAD (max) is specified as a reference point only. If tRAD is greater than the specified tRAD (max) limit, then access time is controlled by tAA. 13) For CAS-before-RAS cycles only. Semiconductor Group 609
