Features  
Clocking and Addressing Schemes  
• Simultaneous Read and Write SigmaQuad™ Interface  
• JEDEC-standard pinout and package  
• Dual Double Data Rate interface  
• Byte Write controls sampled at data-in time  
• Burst of 4 Read and Write  
• 1.8 V +100/–100 mV core power supply  
• 1.5 V or 1.8 V HSTL Interface  
• Pipelined read operation  
• Fully coherent read and write pipelines  
• ZQ pin for programmable output drive strength  
• IEEE 1149.1 JTAG-compliant Boundary Scan  
• Pin-compatible with present 9Mb and future 36Mb and  
144Mb devices  
The GS8182D08/09/18/36BD SigmaQuad-II SRAMs are  
synchronous devices. They employ two input register clock  
inputs, K and K. K and K are independent single-ended clock  
inputs, not differential inputs to a single differential clock input  
buffer. The device also allows the user to manipulate the  
output register clock inputs quasi independently with the C and  
C clock inputs. C and C are also independent single-ended  
clock inputs, not differential inputs. If the C clocks are tied  
high, the K clocks are routed internally to fire the output  
registers instead.  
Each internal read and write operation in a SigmaQuad-II B4  
RAM is four times wider than the device I/O bus. An input  
data bus de-multiplexer is used to accumulate incoming data  
before it is simultaneously written to the memory array. An  
output data multiplexer is used to capture the data produced  
from a single memory array read and then route it to the  
appropriate output drivers as needed. Therefore the address  
field of a SigmaQuad-II B4 RAM is always two address pins  
less than the advertised index depth (e.g., the 2M x 8 has a  
512K addressable index).  
• 165-bump, 13 mm x 15 mm, 1 mm bump pitch BGA package  
• RoHS-compliant 165-bump BGA package available  
SigmaQuadFamily Overview  
The GS8182D08/09/18/36BD are built in compliance with  
the SigmaQuad-II SRAM pinout standard for Separate I/O  
synchronous SRAMs. They are 18,874,368-bit (18Mb)  
SRAMs. The GS8182D08/09/18/36BD SigmaQuad SRAMs  
are just one element in a family of low power, low voltage  
HSTL I/O SRAMs designed to operate at the speeds needed to  
implement economical high performance networking systems.

Background  
Separate I/O SRAMs, from a system architecture point of view, are attractive in applications where alternating reads and writes are  
needed. Therefore, the SigmaQuad-II SRAM interface and truth table are optimized for alternating reads and writes. Separate I/O  
SRAMs are unpopular in applications where multiple reads or multiple writes are needed because burst read or write transfers from  
Separate I/O SRAMs can cut the RAM’s bandwidth in half.  
SigmaQuad-II B4 SRAM DDR Read  
The status of the Address Input, W, and R pins are sampled by the rising edges of K. W and R high causes chip disable. A low on  
the Read Enable-bar pin, R, begins a read cycle. R is always ignored if the previous command loaded was a read command. Data  
can be clocked out after the next rising edge of K with a rising edge of C (or by K if C and C are tied high), after the following  
rising edge of K with a rising edge of C (or by K if C and C are tied high), after the next rising edge of K with a rising edge of C,  
and after the following rising edge of K with a rising edge of C. Clocking in a high on the Read Enable-bar pin, R, begins a read  
port deselect cycle.

The status of the Address Input, W, and R pins are sampled by the rising edges of K. W and R high causes chip disable. A low on  
the Write Enable-bar pin, W, and a high on the Read Enable-bar pin, R, begins a write cycle. W is always ignored if the previous  
command was a write command. Data is clocked in by the next rising edge of K, the rising edge of K after that, the next rising edge  
of K, and finally by the next rising edge of K. and by the rising edge of the K that follows.

2. After power is achieved and clocks (K, K, C, C) are stablized, change Doff to high.  
3. An additional 1024 clock cycles are required to lock the DLL after it has been enabled.  
Note:  
If you want to tie Doff high with an unstable clock, you must stop the clock for a minimum of 30 ns to reset the DLL after  
the clocks become stablized.  
DLL Constraints  
• The DLL synchronizes to either K or C clock. These clocks should have low phase jitter (t  
)
KCVar.  
• The DLL cannot operate at a frequency lower than that specified by the t  
maximum specification for the desired  
KHKH  
operating clock frequency.  
• If the incoming clock is not stablized when DLL is enabled, the DLL may lock on the wrong frequency and cause  
undefined errors or failures during the initial stage.  
Note:  
If the frequency is changed, DLL reset is required. After reset, a minimum of 1024 cycles is required for DLL lock.

Special Functions  
Byte Write and Nybble Write Control  
Byte Write Enable pins are sampled at the same time that Data In is sampled. A high on the Byte Write Enable pin associated with  
a particular byte (e.g., BW0 controls D0–D8 inputs) will inhibit the storage of that particular byte, leaving whatever data may be  
stored at the current address at that byte location undisturbed. Any or all of the Byte Write Enable pins may be driven high or low  
during the data in sample times in a write sequence.  
Each write enable command and write address loaded into the RAM provides the base address for a 4 beat data transfer. The x18  
version of the RAM, for example, may write 72 bits in association with each address loaded. Any 9-bit byte may be masked in any  
write sequence.  
Nybble Write (4-bit) control is implemented on the 8-bit-wide version of the device. For the x8 version of the device, “Nybble  
Write Enable” and “NBx” may be substituted in all the discussion above.

Output Register Control  
SigmaQuad-II SRAMs offer two mechanisms for controlling the output data registers. Typically, control is handled by the Output  
Register Clock inputs, C and C. The Output Register Clock inputs can be used to make small phase adjustments in the firing of the  
output registers by allowing the user to delay driving data out as much as a few nanoseconds beyond the next rising edges of the K  
and K clocks. If the C and C clock inputs are tied high, the RAM reverts to K and K control of the outputs, allowing the RAM to  
function as a conventional pipelined read SRAM.

FLXDrive-II Output Driver Impedance Control  
HSTL I/O SigmaQuad-II SRAMs are supplied with programmable impedance output drivers. The ZQ pin must be connected to  
via an external resistor, RQ, to allow the SRAM to monitor and adjust its output driver impedance. The value of RQ must be  
V
SS  
5X the value of the desired RAM output impedance. The allowable range of RQ to guarantee impedance matching continuously is  
between 175Ω and 350Ω. Periodic readjustment of the output driver impedance is necessary as the impedance is affected by drifts  
in supply voltage and temperature. The SRAM’s output impedance circuitry compensates for drifts in supply voltage and  
temperature. A clock cycle counter periodically triggers an impedance evaluation, resets and counts again. Each impedance  
evaluation may move the output driver impedance level one step at a time towards the optimum level. The output driver is  
implemented with discrete binary weighted impedance steps.

If C, C are tied high, K, K become the references for C, C timing parameters  
To avoid bus contention, at a given voltage and temperature tCHQX1 is bigger than tCHQZ. The specs as shown do not imply bus contention because tCHQX1 is a MIN parameter  
that is worst case at totally different test conditions (0°C, 1.9 V) than tCHQZ, which is a MAX parameter (worst case at 70°C, 1.7 V). It is not possible for two SRAMs on the same  
board to be at such different voltages and temperatures.

Clock phase jitter is the variance from clock rising edge to the next expected clock rising edge.  
VDD slew rate must be less than 0.1 V DC per 50 ns for DLL lock retention. DLL lock time begins once VDD and input clock are stable.  
8.  
Echo clock is very tightly controlled to data valid/data hold. By design, there is a ±0.1 ns variation from echo clock to data. The datasheet parameters reflect tester guard bands  
and test setup variations.

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  
.
DD  
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.

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 or TAP 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.

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.

GS8182D08/09/18/36BD-400/375/333/300/250/200/167  
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.
