K4Q153211M, K4Q153212M  
CMOS DRAM  
512K x 32Bit CMOS Quad CAS DRAM with EDO  
DESCRIPTION  
This is a 524,288 x 32 bit Extended Data Out CMOS DRAM. Extended Data Out Mode offers high speed random access of memory cells  
within the same row, so called Hyper Page Mode. Power supply voltage (+5.0V or +3.3V), refresh cycle 1K, access time (-50 or -60),  
power consumption(Normal or Low power) and SOJ package type 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. This  
512Kx32 EDO Mode Quad CAS DRAM is fabricated using Samsung's advanced CMOS process to realize high band-width, low power  
consumption and high reliability.
