Description  
The IBM041840QLAD and IBM043640QLAD 4Mb  
SRAMS are Synchronous Flow-Thru Mode, high  
performance CMOS Static Random Access Memo-  
ries that are versatile, wide I/O, and achieve 4.5ns  
cycle time. Dual differential K clocks are used to ini-  
tiate the read/write operation, and all internal opera-  
tions are self-timed. At the rising edge of the K  
Clock, all Addresses, Write-Enables, Sync Select,  
and Data Ins are registered internally. Differential  
clocks C and C are used to control the Output Data  
hold time by allowing output data to change after the  
rising edge of the C clock. An internal Write buffer  
allows write data to follow one cycle after addresses  
and controls. The chip is operated with a +3.3V  
power supply, output power supply compatible with  
1.5V, and is also compatible with HSTL I/O inter-  
faces.
