Functional Description
The GS881Z18B(T/D)/GS881Z32B(T/D)/GS881Z36B(T/D) is a 9Mbit 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.

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
• On-chip write parity checking; even or odd selectable
• 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 Interleave Burst mode
• Pin-compatible with 2M, 4M, and 18M devices
• Byte write operation (9-bit Bytes)
• 3 chip enable signals for easy depth expansion
• ZZ pin for automatic power-down
• JEDEC-standard packages
• Pb-Free 100-lead TQFP package available
