Abstract— Power optimization has become increasingly
critical in the VLSI industry due to the rising density of
memory systems, which leads to higher power consumption.
Static RAM (SRAM) cells are particularly affected by this
issue. A significant contributor to power consumption is the
leakage current in transistors. Therefore, decreasing power
consumption in each memory cell is essential. This paper
focuses on optimizing the power of various 12T SRAM cells
through an analysis of the transistor stacking technique.
Instead of relying a single larger transistor, two smaller
transistors are connected in series and switched off together.
This configuration reduces leakage current, thereby decreasing
power consumption in SRAM cells. The power usage of SRAM
cells in presence and absence of the stacking method, is
evaluated under different voltage conditions and performed
simulations in Cadence Virtuoso.
Keywords—Stacking, SRAM, FinFET, power consumption
I. INTRODUCTION
The design of semiconductor devices has advanced
significantly with the development of Fin Field-Effect
Transistors (FinFETs), especially as the market shifts to
transistors that are more compact and power-efficient. As
device dimensions decrease to nanometer scales,
conventional planar transistors have encountered difficulties
in managing leakage currents and short-channel effects [1].
Due to these difficulties, FinFETs which provide enhanced
performance, power efficiency, and scalability have been
developed and adopted [2].
FinFETs are a type of 3D transistor where the conducting
channel is wrapped by a thin, fin-shaped silicon structure.
Unlike conventional planar transistors, which have a single
gate, FinFETs typically feature multiple gates that surround
the fin on three sides [3]. This multi-gate configuration
allows for better control over the channel, significantly
reducing leakage currents and improving the overall
performance of the device. The enhanced gate control also
minimizes the short channel effects that plague traditional
transistors at smaller nodes [4].
The ability of FinFET technology to function at lower
voltages while maintaining great performance is one of its
fundamental features. Because of this, FinFETs are
especially appealing for applications like data centers, high-
performance computing, and mobile devices where power
efficiency is critical. In addition to extending battery life in
portable devices, FinFET’s lower power consumption helps
control heat dissipation in closely spaced circuits, enabling
higher integration densities [5].
FinFETs provide enhanced switching speeds and decreased
variability in addition to power efficiency, which is critical
for scaling to advanced technology nodes like 7nm and
beyond [6]. Modern CPUs and memory components are
built using FinFETs because of their reliable performance at
these scales [7]. FinFETs are predicted to be crucial in
enabling future miniaturization and performance
improvements in electronic devices as the semiconductor
industry pushes the limits of Moore's Law [8].
By offering better control over leakage currents and short-
channel effects, FinFET technology overcomes the
drawbacks of conventional planar transistors and produces
notable gains in performance and power efficiency. FinFETs
are expected to stay a mainstay of contemporary
semiconductor design as the market develops, spurring
innovation in a variety of applications from high-
performance computing systems to mobile devices [9].
