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.  
Features  
• IEEE 1149.1 JTAG-compatible Boundary Scan  
• 2.5 V or 3.3 V +10%/–10% core power supply  
• 2.5 V or 3.3 V I/O supply  
• LBO pin for Linear or Interleaved Burst mode  
• Internal input resistors on mode pins allow floating mode pins  
• Byte Write (BW) and/or Global Write (GW) operation  
• Internal self-timed write cycle  
• Automatic power-down for portable applications  
• JEDEC-standard 100-lead TQFP and 165-bump BGA  
packages  
• RoHS-compliant 100-lead TQFP and 165-bump BGA  
packages available  
SCD Pipelined Reads  
The GS88118B(T/D)/GS8813B(T/D)/GS88136B(T/D) is a  
SCD (Single Cycle Desepipelined synchronous SRAM.  
DCD (Dual Cycle Deselecversions are also available. SCD  
SRAMs pipeline deselect commands one stage less than read  
commands. SCD RAMs begin turning off their outputs  
immediately aftethe 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 acontrolled by a  
positive-edge-triggered clock input (CK). Output enable (G)  
and power down control (ZZ) arasynchronous inputs. Burst  
cycles can be initiated with her ADSP or ADSC inputs. In  
Burst mode, subsequent burst addresses are generated  
internally and are controlled by ADV. The burst address  
counter may be confred 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.
