DESCRIPTION  
The ISSI IS61LF/VF102436A and IS61LF/VF204818A  
are high-speed, low-power synchronous static RAMs de-  
signed to provide burstable, high-performance memory for  
communication and networking applications.The IS61LF/

The IS61LF/VF204818Aꢀisꢀorganizedꢀasꢀ2M-wordsꢀbyꢀ18ꢀ

the device integrates a 2-bit burst counter, high-speed  
SRAMꢀcore,ꢀandꢀhigh-driveꢀcapabilityꢀoutputsꢀintoꢀaꢀsingleꢀ  
monolithic circuit. All synchronous inputs pass through  
registers controlled by a positive-edge-triggered single  
clock input.
