Many difficulties have confronted the system-on-chip (SoC) industry during the previous ten years. These difficulties will likely become more significant as more and more applications revolve on the Internet of Everything (IoE). These issues include reducing power consumption for greater energy efficiency, overcoming numerous causes of variation to ensure reliable performance, and reducing design area to save money and boost integration. As a result, chip designers encounter various hurdles when attempting to create stable structures with complicated angles of capability while preserving a small die size and power expenditure. Memory components are among the most critical circuit components on every chip. They account for the majority of the chip's size and power consumption, which has an impact on the overall efficacy and reliability of the chip. These consist of a diverse multitude of serial elements in logic paths, caches, register files, and large memory arrays. In contemporary synchronized CMOS circuits, sequence elements are indispensable components. In fact, they can be responsible for up to 50% of the average number of cells in a semiconductor. We propose a novel methodology aimed at enhancing the reliability of pulsed latches while ensuring that there is no substantial decline in efficiency, area, or power consumption. Furthermore, given that sequential elements can be utilized in creating compact register files, the implementation of pulsed latches in register files is reviewed and compared with other conventional implementations, including static random-access memory (SRAM) and flip-flops. Also shown are new implementations of multiport register files, which are highly beneficial for many applications. The suggested approach has been proven to considerably decrease the enormous excess in area, power consumption, and latency that is typically associated with conventional methods of designing multiport register files
