HYM 328020S/GS-50/-60 8M x 32-Bit
The HYM 328020S/GS-50/-60 is a 32 MByte DRAM module organized as 8 388 608 words by 32-bit in a 72-pin single-in-line package comprising sixteen HYB 5117400BJ 4M x 4 DRAMs in 300 mil wide SOJ-packages mounted together with sixteen 0.2 F ceramic decoupling capacitors on a PC board. The HYM 328020S/GS-50/-60 can also be used as a 16 777 360 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 5117400BJ 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 328020S/GS-50/-60 dictates the use of early write cycles.

Notes:
1) All voltages are referenced to VSS. 2) ICC1, ICC3, ICC4 and ICC6 depend on cycle rate. 3) ICC1 and ICC4 depend on output loading. Specified values are measured with the output open. 4) Address can be changed once or less while RAS = VIL. In the case of ICC4 it can be changed once or less during a fast page mode cycle (tPC). 5) An initial pause of 200 s is required after power-up followed by 8 RAS cycles 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. 6) AC measurements assume tT = 5 ns. 7) VIH (min.) and VIL (max.) are reference levels for measuring timing of input signals. Transition times are also measured between VIH and VIL. 8) Measured with a load equivalent to 2 TTL loads and 100 pF. 9) Operation within the tRCD (max.) limit ensures 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 tCAC. 10)Operation within the tRAD (max.) limit ensures 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. 11)Either tRCH or tRRH must be satisfied for a read cycle. 12)tOFF (max.) define the time at which the outputs achieve the open-circuit condition and are not referenced to output voltage levels . 13)tWCS is not a restrictive operating parameter. This is included in the data sheet as electrical characteristics only. If tWCS > tWCS (min.), the cycle is an early write cycle and the I/O pin will remain open-circuit (high impedance) through the entire cycle. 14)These parameters are referenced to the CAS leading edge.
