FEATURES

GENERAL DESCRIPTION

• 2.5V ±5% Power Supply.

The K7N323645M and K7N321845M are 37,748,736-bits Syn-

• Byte Writable Function.

chronous Static SRAMs.

• Enable clock and suspend operation.

• Single READ/WRITE control pin.

• Self-Timed Write Cycle.

• Three Chip Enable for simple depth expansion with no data

contention .

• A interleaved burst or a linear burst mode.

• Asynchronous output enable control.

• Power Down mode.

• TTL-Level Three-State Outputs.

• 100-TQFP-1420A.

The NtRAM^TM, or No Turnaround Random Access Memory uti-

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

• 165FBGA(11x15 ball aray) with body size of 15mmx17mm.

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 K7N323645M and K7N321845M 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.

K7N323645M

K7N321845M

1Mx36 & 2Mx18 Pipelined NtRAM^TM

FUNCTION DESCRIPTION

The K7N323645M and K7N321845M are NtRAM^TMdesigned to sustain 100% bus bandwidth by eliminating turnaround cycle when

there is transition from Read to Write, or vice versa.

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.

NtRAM^TMlatches external address and initiates a cycle, when CKE, ADV are driven to low and all three chip enables(CS1, CS 2, CS 2)

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(CS 1, 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 pipe-

lined NtRAM^TMuses 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.

Notes : 1. 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.

2. Chip selects must be valid at each rising edge of CLK(when ADV is Low) to remain enabled.

3. 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.

4. 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,2.625V) than tHZC, which is a Max. parameter(worst case at 70°C,2.375V)

It is not possible for two SRAMs on the same board to be at such different voltage and temperature.

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 pend-

ing 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.

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.
