ABSTRACT
SRAM cells are used in many applications such as micro and multi core processor. SRAM cell improves both
read stability and write ability at low supply voltage. The objective is to reduce the power dissipation of a novel
low power 12T SRAM cell. This method removes half-select issue in 6T and 9T SRAM cell. This work proposes
new functional low-power designs of SRAM cells with 6T, 9T and 12 transistors which operate at only 0.4V
power supply in sub-threshold operation at 45 nm technology. The leakage power consumption of the proposed
SRAM cell is thereby reduced compared to that of the conventional six-transistor (6T) SRAM cell. 12T cell
obtains low static power dissipation.
Keywords : SRAM, Micro wind Software, Power consumption, Transistors.
I. INTRODUCTION
An exceptional growth is achieved by electronics
industry over the last two decades, mainly due to
the expeditious advances in integration
technologies, due to the emergence of VLSI. The
number of applications of integrated circuits in
high-performance computing, telecommunications,
and consumer electronics has been progressing
undeviatingly, and at a very instant pace. Typically,
the required computational power of these
applications is the driving exertion for the fast
blooming of domain. The current leading-edge
technologies (such as low bit-rate video and cellular
communications) already provide the end-users a
certain amount of processing power and portability.
This trend is expected to continue, with very
important implications on VLSI and systems design.
One of the most important characteristics of
information services is their increasing need for very
high processing power and bandwidth. The other
important characteristic is that the information
services tend to become more and more
personalized (as opposed to collective services such
as broadcasting), which means that the devices must
be more intelligent to answer individual demands,
and at the same time they must be portable to allow
more flexibility/mobility. As the SRAM cells are
incorporated by latch, the refresh operation isn't
required to keep the data during power on condition
in SRAM cells. Every one of the systems like
microprocessors, hand held gadgets, workstations
have the cache memory which is outlined by SRAM
cells due to its transistor favorable circumstances of
giving quick exchanging and low power utilization.
To store a single bit of data SRAM utilizes four
transistors.
The basic parameters of SRAM cells are the speed
and furnishes multiple designs with the point of
corrupting the power utilization during read write
tasks of SRAM. By considering this need, in this
paper some standard SRAM cell outlines viz. 6T, 7T,
