The K7N403601B and K7N401801B are 4,718,592 bits Syn-
chronous Static SRAMs.
The N

TM
, or No Turnaround Random Access Memory
utilizes all the bandwidth in any combination of operating
cycles.
Address, data inputs, and all control signals except output
enable and linear burst order are synchronized to input clock.
Burst order control must be tied "High or Low".
Asynchronous inputs include the sleep mode enable(ZZ).
Output Enable controls the outputs at any given time.
Write cycles are internally self-timed and initiated by the rising
edge of the clock input. This feature eliminates complex off-
chip write pulse generation
and provides increased timing flexibility for incomming sig-
nals.
For read cycles, pipelined SRAM output data is temporarily
stored by an edge trigered output register and then released
to the output bufferes at the next rising edge of clock.
The K7N403601B and K7N401801B are implemented with
SAMSUNG
′
s high performance CMOS technology and is
available in 100pin TQFP packages. Multiple power and
ground pins minimize ground bounce.
