Features  
The function of the Data Output register can be controlled by  
the user via the FT mode pin (Pin 14). Holding the FT mode  
pin low places the RAM in Flow Through mode, causing  
output data to bypass the Data Output Register. Holding FT  
high places the RAM in Pipeline mode, activating the rising-  
edge-triggered Data Output Register.

The GS88118C(T/D)/GS88132C(88132CT/D)/GS88136C(T/  
D) is a 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.  
Functional Description  
Byte Write and Global Write  
Applications  
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.  
The GS88118C(T/D)/GS88132C(T/D)/GS88136C(T/D) is a  
9,437,184-bit high performance synchronous SRAM with a 2-  
bit 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.  
Sleep Mode  
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.  
Controls  
Addresses, data I/Os, chip enable (E1, E2), 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  
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.  
Core and Interface Voltages  
The GS88118C(T/D)/GS88132C(T/D)/GS88136C(T/D)  
operates on a 2.5 V or 3.3 V power supply. All input are 3.3 V  
and 2.5 V compatible. Separate output power (V  
) pins are  
DDQ  
used to decouple output noise from the internal circuits and are  
3.3 V and 2.5 V compatible.

1. X = Don’t Care, H = High, L = Low  
2. E = T (True) if E2 = 1 and E1 = E3 = 0; E = F (False) if E2 = 0 or E1 = 1 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. 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.  
6. Tying ADSP high and ADSC low allows simple non-burst synchronous operations. See BOLD items above.  
7. 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) 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 gray 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.

Sleep Mode  
During normal operation, ZZ must be pulled low, either by the user or by its internal pull down resistor. When ZZ is pulled high,  
the SRAM will enter a Power Sleep mode after 2 cycles. At this time, internal state of the SRAM is preserved. When ZZ returns to  
low, the SRAM operates normally after ZZ recovery time.  
Sleep mode is a low current, power-down mode in which the device is deselected and current is reduced to I 2. The duration of  
SB  
Sleep mode is dictated by the length of time the ZZ is in a High state. After entering Sleep mode, all inputs except ZZ become  
disabled and all outputs go to High-Z The ZZ pin is an asynchronous, active high input that causes the device to enter Sleep mode.  
When the ZZ pin is driven high, I 2 is guaranteed after the time tZZI is met. Because ZZ is an asynchronous input, pending  
SB  
operations or operations in progress may not be properly completed if ZZ is asserted. Therefore, Sleep mode must not be initiated  
until valid pending operations are completed. Similarly, when exiting Sleep mode during tZZR, only a Deselect or Read commands  
may be applied while the SRAM is recovering from Sleep mode.

Application Tips  
Single and Dual Cycle Deselect  
SCD devices (like this one) 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.

JTAG Port Operation  
Overview  
The JTAG Port on this RAM operates in a manner that is compliant with IEEE Standard 1149.1-1990, a serial boundary scan  
interface standard (commonly referred to as JTAG). The JTAG Port input interface levels scale with V . The JTAG output  
DD  
drivers are powered by V  
.
DDQ  
Disabling the JTAG Port  
It is possible to use this device without utilizing the JTAG port. The port is reset at power-up and will remain inactive unless  
clocked. TCK, TDI, and TMS are designed with internal pull-up circuits.To assure normal operation of the RAM with the JTAG  
Port unused, TCK, TDI, and TMS may be left floating or tied to either V or V . TDO should be left unconnected.

The TDI input is sampled on the rising edge of TCK. This is the input side of the serial registers  
placed between TDI and TDO. The register placed between TDI and TDO is determined by the  
In state of the TAP Controller state machine and the instruction that is currently loaded in the TAP  
Instruction Register (refer to the TAP Controller State Diagram). An undriven TDI pin will produce  
the same result as a logic one input level.  
Output that is active depending on the state of the TAP state machine. Output changes in  
Out response to the falling edge of TCK. This is the output side of the serial registers placed between  
TDI and TDO.  
TDO  
Test Data Out  
Note:  
This device does not have a TRST (TAP Reset) pin. TRST is optional in IEEE 1149.1. The Test-Logic-Reset state is entered while TMS is  
held high for five rising edges of TCK. The TAP Controller is also reset automaticly at power-up.  
JTAG Port Registers  
Overview  
The various JTAG registers, refered to as Test Access Port orTAP Registers, are selected (one at a time) via the sequences of 1s  
and 0s applied to TMS as TCK is strobed. Each of the TAP Registers is a serial shift register that captures serial input data on the  
rising edge of TCK and pushes serial data out on the next falling edge of TCK. When a register is selected, it is placed between the  
TDI and TDO pins.  
Instruction Register  
The Instruction Register holds the instructions that are executed by the TAP controller when it is moved into the Run, Test/Idle, or  
the various data register states. Instructions are 3 bits long. The Instruction Register can be loaded when it is placed between the  
TDI and TDO pins. The Instruction Register is automatically preloaded with the IDCODE instruction at power-up or whenever the  
controller is placed in Test-Logic-Reset state.  
Bypass Register  
The Bypass Register is a single bit register that can be placed between TDI and TDO. It allows serial test data to be passed through  
the RAM’s JTAG Port to another device in the scan chain with as little delay as possible.

Boundary Scan Register  
The Boundary Scan Register is a collection of flip flops that can be preset by the logic level found on the RAM’s input or I/O pins.  
The flip flops are then daisy chained together so the levels found can be shifted serially out of the JTAG Port’s TDO pin. The  
Boundary Scan Register also includes a number of place holder flip flops (always set to a logic 1). The relationship between the  
device pins and the bits in the Boundary Scan Register is described in the Scan Order Table following. The Boundary Scan  
Register, under the control of the TAP Controller, is loaded with the contents of the RAMs I/O ring when the controller is in  
Capture-DR state and then is placed between the TDI and TDO pins when the controller is moved to Shift-DR state. SAMPLE-Z,  
SAMPLE/PRELOAD and EXTEST instructions can be used to activate the Boundary Scan Register.

Identification (ID) Register  
The ID Register is a 32-bit register that is loaded with a device and vendor specific 32-bit code when the controller is put in  
Capture-DR state with the IDCODE command loaded in the Instruction Register. The code is loaded from a 32-bit on-chip ROM.  
It describes various attributes of the RAM as indicated below. The register is then placed between the TDI and TDO pins when the  
controller is moved into Shift-DR state. Bit 0 in the register is the LSB and the first to reach TDO when shifting begins.

Tap Controller Instruction Set  
Overview  
There are two classes of instructions defined in the Standard 1149.1-1990; the standard (Public) instructions, and device specific  
(Private) instructions. Some Public instructions are mandatory for 1149.1 compliance. Optional Public instructions must be  
implemented in prescribed ways. The TAP on this device may be used to monitor all input and I/O pads, and can be used to load  
address, data or control signals into the RAM or to preload the I/O buffers.  
When the TAP controller is placed in Capture-IR state the two least significant bits of the instruction register are loaded with 01.  
When the controller is moved to the Shift-IR state the Instruction Register is placed between TDI and TDO. In this state the desired  
instruction is serially loaded through the TDI input (while the previous contents are shifted out at TDO). For all instructions, the  
TAP executes newly loaded instructions only when the controller is moved to Update-IR state. The TAP instruction set for this  
device is listed in the following table.

Instruction Descriptions  
BYPASS  
When the BYPASS instruction is loaded in the Instruction Register the Bypass Register is placed between TDI and TDO. This  
occurs when the TAP controller is moved to the Shift-DR state. This allows the board level scan path to be shortened to facili-  
tate testing of other devices in the scan path.  
SAMPLE/PRELOAD  
SAMPLE/PRELOAD is a Standard 1149.1 mandatory public instruction. When the SAMPLE / PRELOAD instruction is  
loaded in the Instruction Register, moving the TAP controller into the Capture-DR state loads the data in the RAMs input and  
I/O buffers into the Boundary Scan Register. Boundary Scan Register locations are not associated with an input or I/O pin, and  
are loaded with the default state identified in the Boundary Scan Chain table at the end of this section of the datasheet. Because  
the RAM clock is independent from the TAP Clock (TCK) it is possible for the TAP to attempt to capture the I/O ring contents  
while the input buffers are in transition (i.e. in a metastable state). Although allowing the TAP to sample metastable inputs will  
not harm the device, repeatable results cannot be expected. RAM input signals must be stabilized for long enough to meet the  
TAPs input data capture set-up plus hold time (tTS plus tTH). The RAMs clock inputs need not be paused for any other TAP  
operation except capturing the I/O ring contents into the Boundary Scan Register. Moving the controller to Shift-DR state then  
places the boundary scan register between the TDI and TDO pins.  
EXTEST  
EXTEST is an IEEE 1149.1 mandatory public instruction. It is to be executed whenever the instruction register is loaded with  
all logic 0s. The EXTEST command does not block or override the RAM’s input pins; therefore, the RAM’s internal state is  
still determined by its input pins.

GS88118/32/36C(T/D)-xxx  
Typically, the Boundary Scan Register is loaded with the desired pattern of data with the SAMPLE/PRELOAD command.  
Then the EXTEST command is used to output the Boundary Scan Register’s contents, in parallel, on the RAM’s data output  
drivers on the falling edge of TCK when the controller is in the Update-IR state.  
Alternately, the Boundary Scan Register may be loaded in parallel using the EXTEST command. When the EXTEST instruc-  
tion is selected, the sate of all the RAM’s input and I/O pins, as well as the default values at Scan Register locations not asso-  
ciated with a pin, are transferred in parallel into the Boundary Scan Register on the rising edge of TCK in the Capture-DR  
state, the RAM’s output pins drive out the value of the Boundary Scan Register location with which each output pin is associ-  
ated.  
IDCODE  
The IDCODE instruction causes the ID ROM to be loaded into the ID register when the controller is in Capture-DR mode and  
places the ID register between the TDI and TDO pins in Shift-DR mode. The IDCODE instruction is the default instruction  
loaded in at power up and any time the controller is placed in the Test-Logic-Reset state.  
SAMPLE-Z  
If the SAMPLE-Z instruction is loaded in the instruction register, all RAM outputs are forced to an inactive drive state (high-  
Z) and the Boundary Scan Register is connected between TDI and TDO when the TAP controller is moved to the Shift-DR  
state.

Notes:  
1. Customers requiring delivery in Tape and Reel should add the character “T” to the end of the part number. Example: GS88118CT-150T.  
2. The speed column indicates the cycle frequency (MHz) of the device in Pipeline mode and the latency (ns) in Flow Through mode. Each  
device is Pipeline/Flow Through mode-selectable by the user.  
3. T = C = Commercial Temperature Range.
