Summary, etc Memory arrays are an important part of any digital integrated system. Over the years, due to the dawn of low power and high integrated density electronic gadgets such as Mobile, Computers etc. there was a great necessity of technology progression in memory chip design. Static random access memory (SRAM) has also gone through these technology advancement phases. Many topologies of SRAM cell and other peripherals which are used in memory blockhave been proposed over the years to reduce the power consumption as well as area of system on chip (SoC). In memories, there is always a tradeoff between power consumption and speedof operation. Hence, it is always a challenging task in memory designing to keep both these parameters i.e. Power consumption and speed balanced, while keeping minimum area of SoC. A conventional 6T SRAM cell dominates among various other topologies such as 8T, 5T, 4T and Loadless 4T SRAM cell because of its advantages such as higher cell stability at lower supply voltages and lower process complexity etc. 6T SRAM cell uses two cross coupled CMOS inverters forming a bi-stable latch for data retention. SRAM is a volatile memory which means data stored in it retained till the power is ON. SRAM is generally used in microprocessors as a cache memory because of its high processing speed. In this thesis, a 1KB (1024X8bit) SRAM memory is designed which utilizes 6T SRAM cell as core storing component. This memory block is designed in cadence virtuoso platform with HspiceD simulator using SCL_PDK library in 180 nm CMOS technology which utilizes 1.8 V supply voltage. This SRAM memory comprises of various peripherals circuit for proper read and write operation which are mainly precharge circuit, row decoder, column decoder/mux, word line driver, sense amplifier and write driver circuit therefore these peripherals are also designed and analyzed. The layout of 6T SRAM cell along with other peripherals is drawn considering the minimum area consumption and the Post layout simulation has been performed. Designed SRAM memory was also characterized for cell stability, access time and power consumption during read and write operation. The cell stability in SRAM is quantified as noise margin. Stability analysis of 6T SRAM cell is done by studying butterfly diagram/eye diagram during hold, read and write operation. Static noise margin (hold mode), read noise margin (read mode) and write noise margin (write mode) are found to be 550 mV, 350 mV and 580 mV respectively which matched with high performance 6T SRAM cell demonstrated in 180 nm technology. In memories, access time signifies the performance of the system, for 1KB SRAM memory during Read and write operation it is found to be 5 ns and 3.5 ns respectively. The average power consumption for 1 bit SRAM and 1KB SRAM memory for read and write operation was found to be 43.9 μW and 4.86 mW respectively which are moderate.<br/>
