CMOS DRAM  
4M x 16bit CMOS Dynamic RAM with Fast Page Mode  
DESCRIPTION  
This is a family of 4,194,304 x 16 bit Fast Page Mode CMOS DRAMs. Fast Page Mode offers high speed random access of memory  
cells within the same row. Refresh cycle(4K Ref. or 8K Ref.), access time ( -50 or -60) are optional features of this family. All of this family  
have CAS-before-RAS refresh, RAS-only refresh and Hidden refresh capabilities. This 4Mx16 Fast Page Mode DRAM family is fabri-  
cated using Samsung¢s advanced CMOS process to realize high band-width, low power consumption and high reliability.  
FEATURES  
• Fast Page Mode operation  
• Part Identification  
• 2CAS Byte/Word Read/Write operation  
• CAS-before-RAS refresh capability  
• RAS-only and Hidden refresh capability  
• Fast parallel test mode capability  
• TTL(5.0V) compatible inputs and outputs  
• Early Write or output enable controlled write  
• JEDEC Standard pinout
