Functional Description

The GS8322Z18/36/72 is a 36Mbit Synchronous Static SRAM. GSIs 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

? 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

? 2.5 V or 3.3 V +10/–10 core power supply

? 2.5 V or 3.3 V I/O supply

? User-configurable Pipeline and Flow Through mode

? ZQ mode pin for user-selectable high/low output drive

? IEEE 1149.1 JTAG-compatible Boundary Scan

? LBO pin for Linear or Interleave Burst mode

? Pin-compatible with 2Mb, 4Mb, 8Mb, and 16Mb devices

? Byte write operation (9-bit Bytes)

? 3 chip enable signals for easy depth expansion

? ZZ Pin for automatic power-down

? JEDEC-standard 119-, 165- or 209-Bump BGA package
