K4F660411B,K4F640411B  
CMOS DRAM  
16M x 4bit CMOS Dynamic RAM with Fast Page Mode  
DESCRIPTION  
This is a family of 16,777,216 x 4 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, -50 or -60), 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 16Mx4  
Fast Page Mode DRAM family is fabricated using Samsung¢s advanced CMOS process to realize high band-width, low power consump-  
tion and high reliability.
