KM48C8000B,KM48C8100B  
CMOS DRAM  
8M x 8bit CMOS Dynamic RAM with Fast Page Mode  
DESCRIPTION  
This is a family of 8,388,608 x 8 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 (-45, -5 or -6), package type (SOJ or TSOP-II) are optional features  
of this family. All of this family have CAS-before-RAS refresh, RAS-only refresh and Hidden refresh capabilities. This 8Mx8 Fast Page  
Mode DRAM family is fabricated using Samsung¢s advanced CMOS process to realize high band-width, low power consumption and  
high reliability.  
• Fast Page Mode operation  
FEATURES  
• CAS-before-RAS refresh capability  
• Part Identification  
• 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
