K4Q170411C, K4Q160411C  
CMOS DRAM  
4M x 4Bit CMOS Quad CAS DRAM with Extended Data Out  
DESCRIPTION  
This is a family of 4,194,304 x 4 bit Quad CAS with Extended Data Out Mode CMOS DRAMs. Extended Data Out Mode offers high  
speed random access of memory cells within the same row, so called Hyper Page Mode. 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 avail-  
able in L-version. Four separate CAS pins provide for seperate I/O operation allowing this device to operate in parity mode.  
This 4Mx4 Extended Data Out Quad CAS DRAM family is fabricated using Samsung¢s advanced CMOS process to realize high band-  
width, low power consumption and high reliability.
