The K7N163631B and K7N161831B are 18,874,368-bits Synchronous Static SRAMs. The NtRAMTM, 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 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 available in 100pin TQFP and 165FBGA packages. Multiple power and ground pins minimize ground bounce.

All inputs (with the exception of OE, LBO and ZZ) are synchronized to rising clock edges. All read, write and deselect cycles are initiated by the ADV input. Subsequent burst addresses can be internally generated by the burst advance pin (ADV). ADV should be driven to Low once the device has been deselected in order to load a new address for next operation. Clock Enable(CKE) pin allows the operation of the chip to be suspended as long as necessary. When CKE is high, all synchronous inputs are ignored and the internal device registers will hold their previous values. NtRAMTM latches external address and initiates a cycle, when CKE, ADV are driven to low and all three chip enables(CS1, CS2, CS2) are active . Output Enable(OE) can be used to disable the output at any given time. Read operation is initiated when at the rising edge of the clock, the address presented to the address inputs are latched in the address register, CKE is driven low, all three chip enables(CS1, CS2, CS2) are active, the write enable input signals WE are driven high, and ADV driven low.The internal array is read between the first rising edge and the second rising edge of the clock and the data is latched in the output register. At the second clock edge the data is driven out of the SRAM. Also during read operation OE must be driven low for the device to drive out the requested data. Write operation occurs when WE is driven low at the rising edge of the clock. BW[d:a] can be used for byte write operation. The pipelined NtRAMTM uses a late-late write cycle to utilize 100% of the bandwidth. At the first rising edge of the clock, WE and address are registered, and the data associated with that address is required two cycle later. Subsequent addresses are generated by ADV High for the burst access as shown below. The starting point of the burst seguence is provided by the external address. The burst address counter wraps around to its initial state upon completion. The burst sequence is determined by the state of the LBO pin. When this pin is low, linear burst sequence is selected. And when this pin is high, Interleaved burst sequence is selected. During normal operation, ZZ must be driven low. When ZZ is driven high, the SRAM will enter a Power Sleep Mode after 2 cycles. At this time, internal state of the SRAM is preserved. When ZZ returns to low, the SRAM normally operates after 2 cycles of wake up time.

The above parameters are also guaranteed at industrial temperature range. 2. All address inputs must meet the specified setup and hold times for all rising clock(CLK) edges when ADV is sampled low and CS is sampled low. All other synchronous inputs must meet the specified setup and hold times whenever this device is chip selected. 3. Chip selects must be valid at each rising edge of CLK(when ADV is Low) to remain enabled. 4. A write cycle is defined by WE low having been registered into the device at ADV Low, A Read cycle is defined by WE High with ADV Low, Both cases must meet setup and hold times. 5. To avoid bus contention, At a given voltage and temperature tLZC is more than tHZC. The specs as shown do not imply bus contention because tLZC is a Min. parameter that is worst case at totally different test conditions (0°C,3.465V) than tHZC, which is a Max. parameter(worst case at 70°C,3.135V) It is not possible for two SRAMs on the same board to be at such different voltage and temperature. - 13 - Jan. 2005 Rev 0.4 Preliminary K7N163631B K7N161831B 512Kx36 & 1Mx18 Pipelined NtRAMTM SLEEP MODE SLEEP MODE is a low current, power-down mode in which the device is deselected and current is reduced to ISB2. The duration of SLEEP MODE is dictated by the length of time the ZZ is in a High state. After entering SLEEP MODE, all inputs except ZZ become disabled and all outputs go to High-Z The ZZ pin is an asynchronous, active high input that causes the device to enter SLEEP MODE. When the ZZ pin becomes a logic High, ISB2 is guaranteed after the time tZZI is met. Any operation pending when entering SLEEP MODE is not guaranteed to successful complete. Therefore, SLEEP MODE (READ or WRITE) must not be initiated until valid pending operations are completed. similarly, when exiting SLEEP MODE during tPUS, only a DESELECT or READ cycle should be given while the SRAM is transitioning out of SLEEP MODE.

The package pads are monitored by the Serial Scan circuitry when in test mode. This is to support connectivity testing during manufacturing and system diagnostics. Internal data is not driven out of the SRAM under JTAG control. In conformance with IEEE 1149.1, the SRAM contains a TAP controller, Instruction Register, Bypass Register and ID register. The TAP controller has a standard 16-state machine that resets internally upon power-up, therefore, TRST signal is not required. It is possible to use this device without utilizing the TAP. To disable the TAP controller without interfacing with normal operation of the SRAM, TCK must be tied to VSS to preclude mid level input. TMS and TDI are designed so an undriven input will produce a response identical to the application of a logic 1, and may be left unconnected. But they may also be tied to VDD through a resistor. TDO should be left unconnected. JTAG Block Diagram JTAG Instruction Coding IR2 IR1 IR0 SRAM CORE TDI BYPASS Reg. TDO Identification Reg. Instruction Reg.
