Functional Description
3T-iRAM™ is a unique type of dynamic memory. Tezzaron
has crafted these pseudostatic devices to provide entirely
SRAM-compatible interfaces and timing. The unique design
of these 3T memories provides soft error rates up to 10
times lower than equivalent high-speed, high-density
SRAMs.
The TSC2L72T18/36/72 is a 72Mbit synchronous memory
device that functions much like ZBT, NtRAM, NoBL, and
other pipelined read/double late write SRAMs – it exploits all
available bus bandwidth by eliminating “deselect cycles”
when the device is switched from read to write.
As in all synchronous devices, address, data inputs, and
read/write control inputs are captured on the rising clock
edge. Burst order control (
LBO
) must be tied to a power rail
for proper operation. Asynchronous inputs include the Sleep
mode enable (ZZ) and Output Enable (
G
). Output Enable
can override the synchronous control of the output drivers to
turn them off at any time. Write cycles are internally self-
timed and initiated by the rising clock edge; this eliminates
the complex off-chip write pulse generation required by
asynchronous SRAMs and simplifies input signal timing.
The TSC2L72T18/36/72 is pipelined, with a rising-edge-
triggered output register. For read cycles, output data is
stored in the edge-triggered output register during the
access cycle and then released to the output drivers at the
next rising clock edge.
