The HYM 361120/40S/GS-60/-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
1 DRAMs and eight
HYB 514400BJ 1M
4 DRAMs in 300 mil wide SOJ-packages mounted together with twelve
0.2
F ceramic decoupling capacitors on a PC board.
The HYM 361120/40S/GS-60/-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 HYM 361120/40S/GS-60/-70 dictates the use of early write cycles.

Notes
1) All voltages are referenced to
V
SS
.
2)
I
CC1
,
I
CC3
,
I
CC4
and
I
CC6
depend on cycle rate.
3)
I
CC1
and
I
CC4
depend on output loading. Specified values are measured with the output open.
4) An initial pause of 200
s 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)
V
IH
(min.)
and
V
IL
(max.)
are reference levels for measuring timing of input signals. Transition times are also
measured between
V
IH
and
V
IL
.
6) Measured with a load equivalant of 2 TTL loads and 100 pF.
7)
t
OFF
(max.)
defines the time at which the output achieves the open-circuit condition and is not referenced to
output voltage levels.
8) Either
t
RCH
or
t
RRH
must be satisfied for a read cycle.
9) These parameters are referenced to the CAS leading edge.
10)
t
WCS
is not a restrictive operating parameter. This is included in the data sheet as electrical characteristic only.
If
t
WCS
>
t
WCS
(min.)
, the cycle is an early write cycle and data out pin will remain open circuit (high impedance).
11) Operation within the
t
RCD
(max.)
limit insures that
t
RAC
(max.)
can be met.
t
RCD
(max.)
is specified as a reference
point only. If
t
RCD
is greater than the specified
t
RCD
(max.)
limit, then access time is controlled by
t
CAC
.
12) Operation within the
t
RAD
(max.)
limit insures that
t
RAC
(max.)
can be met.
t
RAD
(max.)
is specified as a reference
point only. If
t
RAD
is greater than the specified
t
RAD
(max.)
limit, then access time is controlled by
t
AA
.
13) For CAS-before-RAS cycles only.
