GENERAL DESCRIPTION
The K7M163625A and K7M161825A are 18,874,368-bits Syn-
chronous Static SRAMs.
The NtRAM
TM
, or No Turnaround Random Access Memory uti-
lizes all 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, Flow-Through SRAM allows output data to
simply flow freely from the memory array.
The K7M163625A and K7M161825A are implemented with
SAMSUNG′s high performance CMOS technology and is avail-
able in 100pin TQFP packages. Multiple power and ground pins
minimize ground bounce.
