Functional Description
180 MHz–100 MHz
3.3 V VDD
3.3 V and 2.5 V I/O
counter may be configured to count in either linear or
interleave order with the Linear Burst Order (LBO) input. The
burst function need not be used. New addresses can be loaded
on every cycle with no degradation of chip performance.
Flow Through/Pipeline Reads
The function of the Data Output register can be controlled by
the user via the FT mode pin/bump (pin 14 in the TQFP and
bump 5R in the BGA). Holding the FT mode pin/bump low
places the RAM in Flow Through mode, causing output data to
bypass the Data Output Register. Holding FT high places the
RAM in Pipelined mode, activating the rising-edge-triggered
Data Output Register.
SCD Pipelined Reads
The GS84018/32/36A is an SCD (Single Cycle Deselect)
pipelined synchronous SRAM. DCD (Dual Cycle Deselect)
versions are also available. SCD SRAMs pipeline deselect
commands one stage less than read commands. SCD RAMs
begin turning off their outputs immediately after the deselect
command has been captured in the input registers.
Byte Write and Global Write
Byte write operation is performed by using byte write enable
(BW) input combined with one or more individual byte write
signals (Bx). In addition, Global Write (GW) is available for
writing all bytes at one time, regardless of the Byte Write
control inputs.
Sleep Mode
Applications
The GS84018/32/36A is a 4,718,592-bit (4,194,304-bit for
x32 version) high performance synchronous SRAM with a 2bit burst address counter. Although of a type originally
developed for Level 2 Cache applications supporting high
performance CPUs, the device now finds application in
synchronous SRAM applications ranging from DSP main store
to networking chip set support. The GS84018/32/36A is
available in a JEDEC standard 100-lead TQFP or 119-Bump
BGA package.
Low power (Sleep mode) is attained through the assertion
(High) of the ZZ signal, or by stopping the clock (CK).
Memory data is retained during Sleep mode.
Core and Interface Voltages
The GS84018/32/36A operates on a 3.3 V power supply and
all inputs/outputs are 3.3 V- and 2.5 V-compatible. Separate
output power (VDDQ) pins are used to de-couple output noise
from the internal circuit.
Controls
Addresses, data I/Os, chip enables (E1, E2, E3), address burst
control inputs (ADSP, ADSC, ADV), and write control inputs
(Bx, BW, GW) are synchronous and are controlled by a
positive-edge-triggered clock input (CK). Output enable (G)
and power down control (ZZ) are asynchronous inputs. Burst
cycles can be initiated with either ADSP or ADSC inputs. In
Burst mode, subsequent burst addresses are generated
internally and are controlled by ADV. The burst address

3. All byte I/Os remain High-Z during all write operations regardless of the state of Byte Write Enable inputs.
4. Bytes “C” and “D” are only available on the x32 and x36 versions.

Notes:
1. X = Don’t Care, H = High, L = Low.
2. E = T (True) if E2 = 1 and E3 = 0; E = F (False) if E2 = 0 or E3 = 1.
3. W = T (True) and F (False) is defined in the Byte Write Truth Table preceding.
4. G is an asynchronous input. G can be driven high at any time to disable active output drivers. G low can only enable active drivers (shown
as “Q” in the Truth Table above).
5.
6.
7.
All input combinations shown above are tested and supported. Input combinations shown in gray boxes need not be used to accomplish
basic synchronous or synchronous burst operations and may be avoided for simplicity.
Tying ADSP high and ADSC low allows simple non-burst synchronous operations. See BOLD items above.
Tying ADSP high and ADV low while using ADSC to load new addresses allows simple burst operations. See ITALIC items above.

Notes:
1. The diagram shows only supported (tested) synchronous state transitions. The diagram presumes G is tied Low.
2. The upper portion of the diagram assumes active use of only the Enable (E1, E2, E3) and Write (BA, BB, BC, BD, BW and GW) control inputs
and that ADSP is tied high and ADSC is tied low.
3. The upper and lower portions of the diagram together assume active use of only the Enable, Write and ADSC control inputs and assumes
ADSP is tied high and ADV is tied low.

Notes:
1. The diagram shows supported (tested) synchronous state transitions plus supported transitions that depend upon the use of G.
2. Use of “Dummy Reads” (Read Cycles with G High) may be used to make the transition from Read cycles to Write cycles without passing
through a Deselect cycle. Dummy Read cycles increment the address counter just like normal Read cycles.
3. Transitions shown in grey tone assume G has been pulsed high long enough to turn the RAM’s drivers off and for incoming data to meet
Data Input Set Up Time.

2. This device features input buffers compatible with both 3.3 V and 2.5 V I/O drivers.
3. Most speed grades and configurations of this device are offered in both Commercial and Industrial Temperature ranges. The part number of
Industrial Temperature Range versions end the character “I”. Unless otherwise noted, all performance specifications quoted are evaluated
for worst case in the temperature range marked on the device.

Application Tips
Single and Dual Cycle Deselect
SCD devices force the use of “dummy read cycles” (read cycles that are launched normally but that are ended with the output
drivers inactive) in a fully synchronous environment. Dummy read cycles waste performance but their use usually assures there
will be no bus contention in transitions from reads to writes or between banks of RAMs. DCD SRAMs do not waste bandwidth on
dummy cycles and are logically simpler to manage in a multiple bank application (wait states need not be inserted at bank address
boundary crossings), but greater care must be exercised to avoid excessive bus contention.

Notes:
1. Customers requiring delivery in Tape and Reel should add the character “T” to the end of the part number. Example: GS84032AT-8T.
2. The speed column indicates the cycle frequency (MHz) of the device in Pipelined mode and the latency (ns) in Flow Through mode.
Each device is Pipeline/Flow through mode-selectable by the user.
3. TA = C = Commercial Temperature Range. TA = I = Industrial Temperature Range.
4. GSI offers other versions this type of device in many different configurations and with a variety of different features, only some of which
are covered in this data sheet. See the GSI Technology web site (www.gsitechnology.com) for a complete listing of current offerings.
