1.8 V, 2.5 V, or 3.3 V I/O  
Because it is a synchronous device, address, data inputs, and  
read/ write control inputs are captured on the rising edge of the  
input clock. Burst order control (LBO) must be tied to a power  
rail for proper operation. Asynchronous inputs include the  
Sleep mode enable, ZZ and Output Enable. Output Enable can  
be used to override the synchronous control of the output  
drivers and turn the RAM's output drivers off at any time.  
Write cycles are internally self-timed and initiated by the rising  
edge of the clock input. This feature eliminates complex off-  
chip write pulse generation required by asynchronous SRAMs  
and simplifies input signal timing.  
Features  
• User-configurable Pipeline and Flow Through mode  
• NBT (No Bus Turn Around) functionality allows zero wait  
read-write-read bus utilization  
• Fully pin-compatible with both pipelined and flow through  
NtRAM™, NoBL™ and ZBT™ SRAMs  
• IEEE 1149.1 JTAG-compatible Boundary Scan  
• 1.8 V, 2.5 V, or 3.3 V +10%/–10% core power supply  
• LBO pin for Linear or Interleave Burst mode  
• Pin-compatible with 2Mb, 4Mb, 8Mb, 36Mb, 72Mb and  
144Mb devices  
• Byte write operation (9-bit Bytes)  
• 3 chip enable signals for easy depth expansion  
• ZZ pin for automatic power-down  
• JEDEC-standard 165-bump BGA package  
• RoHS-compliant 100-pin TQFP and 165-bump BGA  
packages available  
The GS8161Z18D(GT/D)/GS8161Z32D(D)/  
GS8161Z36D(GT/D) may be configured by the user to operate  
in Pipeline or Flow Through mode. Operating as a pipelined  
synchronous device, in addition to the rising-edge-triggered  
registers that capture input signals, the device incorporates a  
rising-edge-triggered output register. For read cycles, pipelined  
SRAM output data is temporarily stored by the edge triggered  
output register during the access cycle and then released to the  
output drivers at the next rising edge of clock.  
Functional Description  
The GS8161Z18D(GT/D)/GS8161Z32D(D)/  
GS8161Z36D(GT/D) is an 18Mbit Synchronous Static SRAM.  
GSI's NBT SRAMs, like ZBT, NtRAM, NoBL or other  
pipelined read/double late write or flow through read/single  
late write SRAMs, allow utilization of all available bus  
bandwidth by eliminating the need to insert deselect cycles  
when the device is switched from read to write cycles.  
The GS8161Z18D(GT/D)/GS8161Z32D(D)/  
GS8161Z36D(GT/D) is implemented with GSI's high  
performance CMOS technology and is available in JEDEC-  
standard 165-bump BGA package.
