HYB 3117800BSJ-50/-60/-70
2M x 8-DRAM
The HYB 3117800BSJ is a 16 MBit dynamic RAM organized as 2097152 words by 8-bits. The HYB
3117800BSJ utilizes a submicron CMOS silicon gate process technology, as well as advanced
circuit techniques to provide wide operating margins, both internally and for the system user.
Multiplexed address inputs permit the HYB 3117800BSJ to be packaged in a standard SOJ 28
400 mil plastic package. These packages provide high system bit densities and are compatible with
commonly used automatic testing and insertion equipment. System-oriented features include single
+ 3.3 V (± 0.3V) power supply, direct interfacing with high-performance logic device families.

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 µs 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 100 pF and at Voh=2.0 V (Ioh = -2mA) , Vol=0.8V (Iol=2mA).
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.) and tOEZ (max.) define the time at which the outputs achieve the open-circuit condition and are
not referenced to output voltage levels.
13)Either tDZC or tDZO must be satisfied.
14)Either tCDD or tODD must be satisfied.
15)tWCS, tRWD, tCWD, tAWD and tCPWD are not restrictive operating parameters. They are 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; if tRWD > tRWD (min.), tCWD > tCWD
(min.), tAWD > tAWD (min.) and tCPWD > tCPWD (min.) , the cycle is a read-write cycle and I/O pins will
contain data read from the selected cells. If neither of the above sets of conditions is satisfied, the condition of
the I/O pins (at access time) is indeterminate.
16)These parameters are referenced to the CAS leading edge in early write cycles and to the WE leading edge
in read-write cycles.
17)When using Self Refresh mode, the following refresh operations must be performed to ensure proper DRAM
operation:
If row addresses are being refreshed on an evenly distributed manner over the refresh interval using CBR
refresh cycles, then only one CBR cycle must be performed immediately after exit from Self Refresh.
If row addresses are being refreshed in any other manner (ROR - Distributed/Burst; or CBR-Burst) over the
refresh interval, then a full set of row refreshes must be performed immediately before entry to and immediately
after exit from Self Refresh.

Test Mode Entry

2M x 8-DRAM
Test Mode
As the HYB 3117800BSJ is organized internally as 1M x 16-bits, a test mode cycle using 2:1
compression can be used to improve test time. Note that in the 2M x 8 version the test time is
reduced by 1/2 for a N test pattern.
In a test mode “write” the data from each I/O pin is written into two 1M blocks simultaneously (all “1”
s or all “0” s). In test mode “read” each I/O output is used for indicating the test mode result. If the
internal two bits are equal, the I/O would indicate a “1”. If they were not equal, the I/O would indicate
a “0”. The WCBR cycle (WE, CAS before RAS) puts the device into test mode. To exit from test
mode, a “CAS before RAS refresh”, “RAS only refresh” or “Hidden refresh” can be used. Refresh
during test mode operation can be performed by normal read cycles or by WCBR refresh cylces.
Row addresses A0 through A9 have to kept high to perform a testmode entry cycle. All other
addresses are don’t care.
