Flow Through/Pipeline Reads

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.

SCD Pipelined Reads

The GS88118B(T/D)/GS88132B(T/D)/GS88136B(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 GS88118B(T/D)/GS88132B(T/D)/GS88136B(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 GS88118B(T/D)/GS88132B(T/D)/GS88136B(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.

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. 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.

GS88118B(T/D)/GS88132B(T/D)/GS88136B(T/D)

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.

Description

Clocks all TAP events. All inputs are captured on the rising edge of TCK and all outputs propagate

TCK

In

The TMS input is sampled on the rising edge of TCK. This is the command input for the TAP

TMS

TDI

Test Mode Select

Test Data In

In controller state machine. An undriven TMS input will produce the same result as a logic one input

level.

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.

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.

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.

GS88118B(T/D)/GS88132B(T/D)/GS88136B(T/D)

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.

RFU

These instructions are Reserved for Future Use. In this device they replicate the BYPASS instruction.

Notes:

1. Customers requiring delivery in Tape and Reel should add the character “T” to the end of the part number. Example: GS88118BT-150IT.

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. T = I = Industrial Temperature Range.

A

4. MP = Mass Production. PQ = Pre-Qualification.

5. 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.
