K7N401809B Datasheet | Samsung Semiconductor

DESCRIPTION The K7N403609B and K7N401809B are 4,718,592 bits Synchronous Static SRAMs. The Nt RAMTM, or No Turnaround Random Access Memory utilizes all the bandwidth in any bination 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 plex offchip write pulse generation and provides increased timing flexibility for inming signals. 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 K7N403609B and K7N401809B are implemented with SAMSUNG′s high performance CMOS technology and is available in 100pin TQFP packages. Multiple power and ground pins minimize ground bounce. - VDD=3.3V+0.165V/-0.165V Power Supply. - VDDQ Supply Voltage...
