K7I163682B
K7I161882B
512Kx36 & 1Mx18 DDRII CIO b2 SRAM
GENERAL DESCRIPTION
The K7I163682B and K7I1161882B are 18,874,368-bits DDR Common I/O
Synchronous Pipelined Burst SRAMs.
They are organized as 524,288 words by 36bits for K7I163682B and 1,048,576 words by 18 bits for K7I161882B for K7I160882B.
Address, data inputs, and all control signals are synchronized to the input clock ( K or K ).
Normally data outputs are synchronized to output clocks ( C and C ), but when C and C are tied high,
the data outputs are synchronized to the input clocks ( K and K ).
Read data are referenced to echo clock ( CQ or CQ ) outputs.
Read address and write address are registered on rising edges of the input K clocks.
Common address bus is used to access address both for read and write operations.
The internal burst counter is fixed to 2-bit sequential for both read and write operations.
Synchronous pipeline read and late write enable high speed operations.
Simple depth expansion is accomplished by using LD for port selection.
Byte write operation is supported with BW0 and BW1 ( BW2 and BW3) pins for x18 ( x36 ) device.
Nibble write operation is supported with NW0 and NW1 pins for x8 device.
IEEE 1149.1 serial boundary scan (JTAG) simplifies monitoring package pads attachment status with system.
The K7I163682B and K7I161882B are implemented with SAMSUNG's high performance 6T CMOS technology
and is available in 165pin FBGA packages. Multiple power and ground pins minimize ground bounce.
Read Operations
Read cycles are initiated by initiating R/W as high at the rising edge of the positive input clock K.
Address is presented and stored in the read address register synchronized with K clock.
For 2-bit burst DDR operation, it will access two 36-bit, 18-bit or 8-bit data words with each read command.
The first pipelined data is transferred out of the device triggered by C clock following next K clock rising edge.
Next burst data is triggered by the rising edge of following C clock rising edge.
Continuous read operations are initiated with K clock rising edge.
And pipelined data are transferred out of device on every rising edge of both C and C clocks.
In case C and C tied to high, output data are triggered by K and K instead of C and C.
When the LD is disabled after a read operation, the K7I163682B and K7I161882B will first complete
burst read operation before entering into deselect mode at the next K clock rising edge.
Then output drivers disabled automatically to high impedance state.
Echo clock operation
To assure the output traceability, the SRAM provides the output Echo clock, pair of compliment clock CQ and CQ,
which are synchronized with internal data output.
Echo clocks run free during normal operation.
The Echo clock is triggered by internal output clock signal, and transferred to external through same structures
as output driver.
Power-Up/Power-Down Supply Voltage Sequencing
The following power-up supply voltage application is recommended: VSS, VDD, VDDQ, VREF, then VIN. VDD and VDDQ can be applied
simultaneously, as long as VDDQ does not exceed VDD by more than 0.5V during power-up. The following power-down supply voltage
removal sequence is recommended: VIN, VREF, VDDQ, VDD, VSS. VDD and VDDQ can be removed simultaneously, as long as VDDQ
does not exceed VDD by more than 0.5V during power-down.

K7I161882B
512Kx36 & 1Mx18 DDRII CIO b2 SRAM
Write Operations
Write cycles are initiated by activating R/W as low at the rising edge of the positive input clock K.
Address is presented and stored in the write address register synchronized with next K clock.
For 2-bit burst DDR operation, it will write two 36-bit, 18-bit or 8-bit data words with each write command.
The first “late writed” data is transferred and registered in to the device synchronous with next K clock rising edge.
Next burst data is transferred and registered synchronous with following K clock rising edge.
Continuous write operations are initiated with K rising edge.
And “late writed” data is presented to the device on every rising edge of both K and K clocks.
When the LD is disabled, the K7I163682B and K7I161882B will enter into deselect mode.
The device disregards input data presented on the same cycle W disabled.
The K7I163682B and K7I161882B support byte write operations.
With activating BW0 or BW1 (BW2 or BW3) in write cycle, only one byte of input data is presented.
In K7I161882B, BW0 controls write operation to D0:D8, BW1 controls write operation to D9:D17.
And in K7I163682B BW2 controls write operation to D18:D26, BW3 controls write operation to D27:D35.
Programmable Impedance Output Buffer Operation
The designer can program the SRAM's output buffer impedance by terminating the ZQ pin to VSS through a precision resistor(RQ).
The value of RQ (within 15%) is five times the output impedance desired.
For example, 250Ω resistor will give an output impedance of 50Ω.
Impedance updates occur early in cycles that do not activate the outputs, such as deselect cycles.
In all cases impedance updates are transparent to the user and do not produce access time "push-outs" or other anomalous behav-
ior in the SRAM.
There are no power up requirements for the SRAM. However, to guarantee optimum output driver impedance after power up, the
SRAM needs 1024 non-read cycles.
Clock Consideration
K7I163682B and K7I161882B utilize internal DLL(Delay-Locked Loops) for maximum output data valid window.
It can be placed into a stopped-clock state to minimize power with a modest restart time of 1024 clock cycles.
Circuitry automatically resets the DLL when absence of input clock is detected.
Single Clock Mode
K7I163682B and K7I161882B can be operated with the single clock pair K and K,
instead of C or C for output clocks.
To operate these devices in single clock mode, C and C must be tied high during power up and must be maintained high
during operation.
After power up, this device can′t change to or from single clock mode.
System flight time and clock skew could not be compensated in this mode.
Depth Expansion
Each port can be selected and deselected independently with R/W be shared among all SRAMs and provide a new LD signal
for each bank.
Before chip deselected, all read and write pending operations are completed.

Notes: 1. All address inputs must meet the specified setup and hold times for all latching clock edges.
2. Control signal are R and W.
In case of BW0,BW1 (BW2, BW3, also for x36) signal follow the data setup/hold times.
3. If C,C are tied high, K,K become the references for C,C timing parameters.
4. To avoid bus contention, at a given voltage and temperature tCHQX1 is bigger than tCHQZ.
The specs as shown do not imply bus contention because tCHQX1 is a MIN parameter that is worst case at totally different test conditions
(0°C, 1.9V) than tCHQZ, which is a MAX parameter(worst case at 70°C, 1.7V)
It is not possible for two SRAMs on the same board to be at such different voltage and temperature.
5. Clock phase jitter is the variance from clock rising edge to the next expected clock rising edge.
6. Vdd slew rate must be less than 0.1V DC per 50 ns for DLL lock retention. DLL lock time begins once Vdd and input clock are stable.

IEEE 1149.1 TEST ACCESS PORT AND BOUNDARY SCAN-JTAG
This part contains an IEEE standard 1149.1 Compatible Test Access Port(TAP). 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 Reg-
ister, 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.
