GENERAL DESCRIPTION
chronous Static SRAMs.
The NtRAM
lizes 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 incoming signals.
For read cycles, pipelined SRAM output data is temporarily
stored by an edge triggered output register and then released
to the output buffers at the next rising edge of clock.
The K7N163631B and K7N161803B are implemented with
SAMSUNG′s high performance CMOS technology and is avail-
able in 100pin TQFP and 165FBGA packages. Multiple power
and ground pins minimize ground bounce.
The K7N163631B and K7N161831B are 18,874,368-bits Syn-
