Functional Description
Applications
The GS832218/36/72 is a 37,748,736 -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.
Controls
Addresses, data I/Os, chip enable (E1), address burst control
inputs (ADSP
) are synchronous and are controlled by a positive-edge-
GW
triggered clock input (CK). Output enable (G
control (ZZ) are asynchronous inputs. Burst cycles can be initiated
with either ADSP
burst addresses are generated internally and are controlled by
. The burst address counter may be configured to count in
ADV
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.

) and power down
or ADSC inputs. In Burst mode, subsequent

Flow Through/Pipeline Reads
The function of the Data Output register can be controlled by the
user via the FT mode . Holding the FT mode pin low places the
RAM in Flow Through mode, causing output data to bypass the
Data Output Register. Holding FT
Pipeline mode, activating the rising-edge-triggered Data Output
Register.
SCD and DCD Pipelined Reads
The GS832218/36/72 is a SCD (Single Cycle Deselect) and DCD
(Dual Cycle Deselect) pipelined synchronous SRAM. DCD
SRAMs pipeline disable commands to the same degree as read
commands. 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. DCD RAMs hold the deselect
command for one full cycle and then begin turning off their
outputs just after the second rising edge of clock. The user may
configure this SRAM for either mode of operation using the SCD
mode input.
Byte Write and Global Write
Byte write operation is performed by using Byte Write enable
) input combined with one or more individual byte write
(BW
signals (Bx
). In addition, Global Write (GW) is available for
writing all bytes at one time, regardless of the Byte Write control
inputs.
FLXDrive™
The ZQ pin allows selection between high drive strength (ZQ low)
for multi-drop bus applications and normal drive strength (ZQ
floating or high) point-to-point applications. See the Output Driver
Characteristics chart for details.
Core and Interface Voltages
The GS832218/36/72 operates on a 2.5 V or 3.3 V power supply.

Notes:
1. All byte outputs are active in read cycles regardless of the state of Byte Write Enable inputs.
2. Byte Write Enable inputs B
3. All byte I/Os remain High-Z during all write operations regardless of the state of Byte Write Enable inputs.
4. Bytes “
C” and “ D” are only available on the x36 version.
A, B B, B C, and/or B D may be used in any combination with BW to write single or multiple bytes.
