General Description

The AMIC Zero Bus Latency (ZeBL

) SRAM family

employs high-speed, low-power CMOS designs using an
advanced CMOS process.
The A67P8318, A67P7336 SRAMs integrate a 256K X 18,
128K X 36 SRAM core with advanced synchronous
peripheral circuitry and a 2-bit burst counter. These SRAMs
are optimized for 100 percent bus utilization without the
insertion of any wait cycles during Write-Read alternation.
The positive edge triggered single clock input (CLK) controls
all synchronous inputs passing through the registers. The
synchronous inputs include all address, all data inputs,
active low chip enable (

), two additional chip enables for

easy depth expansion (CE2,

CE2

), cycle start input

(ADV/ LD ), synchronous clock enable (

CEN

), byte write

enables (

BW1

BW2

BW3

BW4

) and read/write (R/

Asynchronous inputs include the output enable (

), clock

(CLK), SLEEP mode (ZZ, tied LOW if unused) and burst
mode (MODE). Burst Mode can provide either interleaved or
linear operation, burst operation can be initiated by
synchronous address Advance/Load (ADV/LD ) pin in Low

state. Subsequent burst address can be internally
generated by the chip and controlled by the same input pin
ADV/LD in High state.

Write cycles are internally self-time and synchronous with
the rising edge of the clock input and when R/

is Low.

The feature simplified the write interface. Individual Byte
enables allow individual bytes to be written.

BW1

controls

I/Oa pins;

BW2

controls I/Ob pins;

BW3

controls I/Oc pins;

and

BW4

controls I/Od pins. Cycle types can only be

defined when an address is loaded.
The SRAM operates from a +2.5V power supply, and all
inputs and outputs are LVTTL-compatible. The device is
ideally suited for high bandwidth utilization systems.

CEN

Synchronous Clock Enable : This active low input permits
CLK to propagate throughout the device. When HIGH, the
device ignores the CLK input and effectively internally
extends the previous CLK cycle. This input must meet setup

Snooze Enable : This active high asynchronous input causes

Read/Write : This active input determines the cycle type
when ADV/LD is LOW. This is the only means for
determining READs and WRITEs. READ cycles may not be
converted into WRITEs (and vice versa) other than by
loading a new address. A LOW on this pin permits BYTE
WRITE operations and must meet the setup and hold times
around the rising edge of CLK. Full bus width WRITEs occur
if all byte write enables are LOW.

Notes:
1. Continue Burst cycles, whether READ or WRITE, use the same control inputs. The type of cycle performed (READ or

WRITE) is chosen in the initial Begin Burst cycle. A Continue Deselect cycle can only be entered if a Deselect cycle is
executed first.

2. Dummy READ and WRITE Abort cycles can be considered NOPs because the device performs no operation. A WRITE

Abort means a WRITE command is given, but no operation is performed.

3. OE may be wired LOW to minimize the number of control signals to the SRAM. The device will automatically turn off the

output drivers during a WRITE cycle. Some users may use OE when the bus turn-on and turn-off times do not meet their
requirements.

4. If an Ignore Clock Edge command occurs during a READ operation, the I/O bus will remain active (Low-Z). If it occurs

during a WRITE cycle, the bus will remain in High-Z. No WRITE operations will be performed during the Ignored Clock
Edge cycle.

5. X means "Don't Care." H means logic HIGH. L means logic LOW.

BWx

= H means all byte write signals (

BW1

BW2

BW3

and

BW4

) are HIGH.

BWx

= L means one or more byte write signals are LOW.

BW1

enables WRITEs to Byte "a" (I/Oa pins);

Notes: 1. This parameter is sampled.

3. Transition is measured

200mV from steady state voltage.

4. OE can be considered a "Don't Care" during WRITE; however, controlling OE can help fine-tune a system for

turnaround timing.

5. This is a synchronous device. All addresses must meet the specified setup and hold times for all rising edges of

CLK when ADV/LD is LOW and chip enabled. All other synchronous inputs meet the setup and hold times with
stable logic levels for all rising edges of clock (CLK) when the chip is enabled. Chip enable must be valid at each
rising edge of CLK (when ADV/LD is LOW) to remain enabled.

SLEEP Mode

SLEEP Mode is a low current "Power-down" mode in which
the device is deselected and current is reduced to I

SB2Z

. This

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 asynchronous, active high input that causes the
device to enter SLEEP Mode. When the ZZ pin becomes
logic HIGH, ISB2Z is guaranteed after the time t

ZZI

is met.

Any operation pending when entering SLEEP Mode is not
guaranteed to successfully complete. Therefore, SLEEP
Mode (READ or WRITE) must not be initiated until valid
pending operations are completed. Similarly, when exiting
SLEEP Mode during t

RZZ

, only a DESELECT or READ cycle

should be given while the SRAM is transitioning out of
SLEEP Mode.

1. For this waveform, ZZ is tied LOW.
2. Burst sequence order is determined by MODE (0 = linear, 1 = interleaved). BRST operations are optional.
