internally and are controlled by ADV. The burst address  
counter may be configured to count in 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.

The GS88037BT-xxxV 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  
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.  
Applications  
The GS88037BT-xxxV is a 9,437,184-bit (8,388,608-bit for  
x32 version) 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.  
Sleep Mode  
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.  
Controls  
Addresses, data I/Os, chip enables (E1, E2, E3), 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  
Core and Interface Voltages  
The GS88037BT-xxxV operates on a 1.8 V or 2.5 V power  
supply. All input are 2.5 V and 1.8 V compatible. Separate  
output power (V  
) pins are used to decouple output noise  
DDQ  
from the internal circuits and are 2.5 V and 1.8 V compatible.
