1.8 V or 2.5 V I/O  
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.  
Features  
• IEEE 1149.1 JTAG-compatible Boundary Scan  
• 1.8 V or 2.5 V +10%/–10% core power supply  
• 1.8 V or 2.5 V I/O supply  
Flow Through/Pipeline Reads  
• 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  
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  
• RoHS-compliant 100-lead TQFP and 165-bump BGA  
packages available  
The GS88118/32/36C(T/D)-xxxIV 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  
Applications  
The GS88118/32/36C(T/D)-xxxIV 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.  
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.  
Controls  
Sleep Mode  
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  
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 GS88118/32/36C(T/D)-xxxIV operates on a 1.8 V or 2.5  
V power supply. All input are 1.8 V and 2.5 V compatible.  
Separate output power (V  
) pins are used to decouple  
DDQ  
output noise from the internal circuits and are 1.8 V and 2.5 V  
compatible.
