Functional Description
The AS7C3364NTF32B/36B family is a high performance CMOS 2 Mbit synchronous Static Random Access Memory
(SRAM) organized as 65,536 words × 32 or 36 bits and incorporates a LATE Write.
This variation of the 2Mb+ synchronous SRAM uses the No Turnaround Delay (NTD
) architecture, featuring an enhanced
write operation that improves bandwidth over flowthrough burst devices. In a normal flowthrough burst device, the write data,
command, and address are all applied to the device on the same clock edge. If a read command follows this write command,
the system must wait for one dead cycle for valid data to become available. This dead cycle can significantly reduce overall
bandwidth for applications requiring random access or read-modify-write operations.
NTD
devices use the memory bus more efficiently by introducing a write latency which matches the one-cycle flow-
through read latency. Write data is applied one cycle after the write command and address, allowing the read pipeline to clear.
With NTD
, write and read operations can be used in any order without producing dead bus cycles.
Assert R/W low to perform write cycles. Byte write enable controls write access to specific bytes, or can be tied low for full 36
bit writes. Write enable signals, along with the write address, are registered on a rising edge of the clock. Write data is applied
to the device one clock cycle later. Unlike some asynchronous SRAMs, output enable OE does not need to be toggled for write
operations; it can be tied low for normal operations. Outputs go to a high impedance state when the device is de-selected by
any of the three chip enable inputs.
Use the ADV (burst advance) input to perform burst read, write and deselect operations. When ADV is high, external addresses, chip
select, R/W pins are ignored, and internal address counters increment in the count sequence specified by the LBO control. Any
device operations, including burst, can be stalled using the CEN=1, the clock enable input.
The AS7C3364NTF32B/36B operates with a 3.3V ± 5% power supply for the device core (V
DD
). DQ circuits use a separate
power supply (V
DDQ
) that operates across 2.5V or 3.3V ranges. These devices are available in a 100-pin TQFP package.

Description
Clock. All inputs except OE, LBO, and ZZ are synchronous to this clock.
Clock enable. When de-asserted high, the clock input signal is masked.
Address. Sampled when all chip enables are active and ADV/LD is asserted.
Data. Driven as output when the chip is enabled and OE is active.
Synchronous chip enables. Sampled at the rising edge of CLK, when ADV/LD is asserted.
Are ignored when ADV/LD is high.
Advance or Load. When sampled high, the internal burst address counter will increment in
the order defined by the LBO input value. When low, a new address is loaded.
A high during LOAD initiates a READ operation. A low during LOAD initiates a WRITE
operation. Is ignored when ADV/LD is high.
Byte write enables. Used to control write on individual bytes. Sampled along with WRITE
command and BURST WRITE.
Asynchronous output enable. I/O pins are not driven when OE is inactive.
Selects Burst mode. When tied to V
DD
or left floating, device follows interleaved Burst order. When
driven Low, device follows linear Burst order.
This signal is internally pulled High.
Snooze. Places device in low power mode; data is retained. Connect to GND if unused.
No connect
Snooze Mode
SNOOZE MODE is a low current, power-down mode in which the device is deselected and current is reduced to I
SB2
. The duration of
SNOOZE MODE is dictated by the length of time the ZZ is in a High state.
The ZZ pin is an asynchronous, active high input that causes the device to enter SNOOZE MODE.
When the ZZ pin becomes a logic High, I
SB2
is guaranteed after the time t
ZZI
is met. After entering SNOOZE MODE, all inputs except ZZ
is disabled and all outputs go to High-Z. Any operation pending when entering SNOOZE MODE is not guaranteed to successfully complete.
Therefore, SNOOZE MODE (READ or WRITE) must not be initiated until valid pending operations are completed. Similarly, when exiting
SNOOZE MODE during t
PUS
, only a DESELECT or READ cycle should be given while the SRAM is transitioning out of SNOOZE MODE.
