Motivation
The static Ram access memory (SRAM) is one of the main memory and it is one of the most important feature of modernized era. SRAM is such a memory chip which is used widely nowadays almost everywhere either it is laptop, mobile phone, and many other devices , etc. SRAM comes under the one of the memory architecture . And SRAM memory advancement is usually used in speed of its light and sufficiency. It works on the number of bits, as the number of bits, increases the memory size as well as the size of the SRAM Chip also increases. And chip designing comes under the field that is VLSI. Nowadays , VLSI is much in need required almost everywhere. As, VLSI become the advancement of field and most trending one as the technology enchances day by day accordingly. So , If we design 6T SRAM cell it is also the part of small memory which is used on small scale but as soon as we go towards the architecture of it - its bits, bytes size as well as the chip size according to in which architecture it is used will be increases accordingly.
Description
The scaling up of CMOS IC technology made the manufacture of quicker and smaller circuits which in the case of SRAM memory has resulted in larger storage capacity and shorter access times. Some percent of the full area of the current System-on-Chip (SoC) is devoted to memory blocks. One result of this reality is that embedded SRAM dominates the general performance. However, with the increasing demand for smaller tool dimensions, layout guidelines, and on-chip cache capacity, the typical 6 transistor cell (6T-cell) has little effect on practical failures. SRAM mobile cell length keeps decreasing through 1/2 of every generation. Despite scaling, SRAM cells need to be stable for the duration of the study and write operations. The maximum vital parameters which might be particularly taken into consideration are threshold voltage, and variability, implying that layout regulations are normally adapted to accommodate power, performance, and region restrictions.
Cell stability for the duration of reading operations is increased with the aid of using strengthening the internal latch inverters and weakening the get entry to transistors, whilst the opposite is preferred for cell Write-capacity: a vulnerable inverter and strong get entry to transistors to have to be selected such that study stability and write-capacity are each inside affordable levels. Based on those constraints it is also assumed that the pull-down transistors of the internal latches of SRAM cells, have to be wider than to get entry to transistors, whilst they get entry to transistors that they need to be, now they are compared with the pull-up transistors (normally they're similarly sized).
The overall cell area is ruled through those constraints. In this project, we look into the opportunity of the use of minimum length transistors to gain a region performance of a 2 transistor cell whilst as compared to standard 6T through retaining the stableness of an SRAM cell inside perfect values. The observation consists of the simulations in addition to experimental measurements from SRAM devices which are fabricated in a sky130 A nm CMOS technology.
Design Goals
The Main Goal of this project is to design and implement a 6T SRAM cell for 1 bit SRAM using CMOS which is a combination of both PMOS and NMOS by using sky130A technology and to study the power consumption, thus Thus, we are predicting that the power dissipation and speed of SRAM will increases. So, the SRAM will not dissipate more heat in future and will work efficiently and be device friendly. So, successful implementation of the design, analysis and fabrication of the proposed circuit will open new doors for the usage of low-power dissipation and consumption.

CMOS devices had been scaled down to be able to reap better pace, performance, and decrease strength consumption. SRAM manner Static Random Access Memory. The SRAM cell or mobile cell that we have taken into thought in this project got to be a 6T SRAM cell or mobile cell which comprises crossly coupled inverters and gets right of section to transistors to consider and compose the information. In the case of the SRAM mobile cell, the memory constructed is being saved across the cross-coupled inverters. If we don't forget that, the input to the primary inverter is logic 1 then the output of this inverter may be logic 0. So, after one cycle the output of the second cross-coupled inverter may be logic 1 at the same time. we will say that so long as the strength is provided to the SRAM cell logic 1 may be circulated withinside the inverters. Hence there's no want for periodic cleaning of the circuit. Whereas in DRAM the circuit wishes to be refreshed periodically. Hence, this SRAM technology has maximum optimum due to its pace and robustness. Therefore, SRAM is a whole lot quicker whilst as compared with DRAM. Hence, it is widely used as compared to DRAM.
