Functional Description
These 36Mb high performance synchronous
SRAMs form a family of device options for those
demanding high performance.
The memory devices contain 36Mb of memory
cells organized as 2,097,152 x 18 (N36N18),
1,048,576 x 36 (N36N36) and 524,288 x 72
(N36N72). The devices operate in a synchronous
manner with control signals, addresses and data
inputs synchronized and captured at the rising
edge of clock for ease of use. An asynchronous
OE is available for disabling the outputs at any
time. An asynchronous ZZ signal can be used to
put the device into sleep mode with all data
retained. User configurable operation in pipeline or
flow-thru modes is allowed through control of the
FT input for BGA devices. Either pipeline or flow-
thru devices are available in TQFP packages. The
devices are fabricated using NanoAmp's advanced
CMOS process and high-speed/ultra low-power
circuit technology.
These 36Mb devices are the type of SRAMs origi-
nally developed as L2 cache memories for high
performance CPUs. They now can be used in
applications ranging from processor caches, DSP
storage and networking memory.
This 36Mb family is ideal for networking and com-
munication systems where high-density, high-per-
formance memory elements are required.
