Design and analysis of low power sram cells

How do SRAM cells work in detail?
A typical SRAM cell is made up of six MOSFETs, and is often called a .
1. T SRAM cell.
How to design SRAM cell?
The SRAM cell must be designed such a way that, during read operation, the changes in Y and Ybar are small enough to prevent the cell from changing its state.
Generally two back to back coupled inverters of the SRAM cell is designed so that Kn and Kp are matched.
This design places the inverter threshold at V_DD/2..
What are the low power techniques for SRAM?
One is the Half-swing Pulse-mode techniques in which a Half-swing Pulse-mode gate family is used that in turn uses reduced input signal swing without sacrificing performance and saves the power.
Second is a memory bank partitioning, in which memory array is partitioned to enhance the speed and to reduce the power..

What is the design of SRAM cell?
SRAM cell is made up of flip flop comprising of two cross coupled inverters.
Two access transistors are used to access the stored data in the cell.
These transistors are turned ON/OFF by the control line called word line(WL).
Generally this word line is connected to the output of row decoder circuits..
Basically, SRAM performs three operations which are Hold, Read and Write operations.
Whenever the two access pass transistors of the word line (WL) are in OFF state, then the bit line and bit line bar (BL & BLB) are also in OFF condition, hence the memory cell is in hold state .
SRAM uses a flip-flop circuit to store each data bit.
The circuit delivers two stable states, which are read as 1 or 0.
To support these states, the circuit requires six transistors, four to store the bit and two to control access to the cell.
The dynamic power of SRAM is dissipated mainly by charging and discharging of the highly capacitive lines.
The largest capacitive element in SRAM is bit-lines because a number of cells connected to it.
More than 50% of the total dynamic power is consumed by driving the bit-lines.

Gated VDD and MTCMOS design techniques have been employed to reduce the power consumed by the SRAM cell. These designs are compared with the conventional 6T SRAM cell. The results show that the MTCMOS based SRAM cell is the best performer in terms of power consumption and write delay.

What are the design challenges associated with the stability of SRAM cell?

Access transistors conflict (cell ratio and pull-up ratio) is another design challenge associated with the stability of SRAM cell

The access transistor width is kept smaller in comparison to the width of the pull-down transistor to improve the read stability of cell

Physical unclonable function (PUF), sometimes also called physically unclonable function, is a physical entity that is embodied in a physical structure and is easy to evaluate but hard to predict.
