K4P170411C, K4P160411C  
CMOS DRAM  
4M x 4Bit CMOS Quad CAS DRAM with Fast Page Mode  
DESCRIPTION  
This is a family of 4,194,304 x 4 bit Quad CAS with Fast Page Mode CMOS DRAMs. Fast Page Mode offers high speed random access  
of memory cells within the same row. Refresh cycle (2K Ref. or 4K Ref.), access time (-50 or -60), power consumption(Normal or Low  
power) and 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. Furthermore, Self-refresh operation is available in L-version. Four separate CAS pins provide for  
seperate I/O operation allowing this device to operate in parity mode.  
This 4Mx4 Fast Page Mode Quad CAS DRAM family is fabricated using Samsung¢s advanced CMOS process to realize high band-  
width, low power consumption and high reliability.
