Functional Description  
The CY7C109 is available in standard 400-mil-wide SOJ and  
32-pin TSOP type I packages. The CY7C1009 is available in  
a 300-mil-wide SOJ package. The CY7C1009 and CY7C109  
are functionally equivalent in all other respects.  
The CY7C109 / CY7C1009 is a high-performance CMOS stat-  
ic RAM organized as 131,072 words by 8 bits. Easy memory  
expansion is provided by an active LOW Chip Enable (CE ),
