Retention time is an important phenomenon in dynamic random access memory for data storage operation. The storage capacitor is solely responsible for charge storing mechanism. The overall action is control by word line and bit line. It is also responsible for sensing, monitoring and data storing operation. Normally the availability of inexpensive leakage reduction technique is the backbone of any dynamic random access memory wherein the valuable sense information is deposited in storage capacitance in electric charge form. Since there is no option available for replenishing the electric charge on storage capacitor to prevent loss of information or data. One of the most acclaimed and accepted schemes toward effecting high retention time is by incorporating the leakage reduction technique which has becomes a part of dynamic random access memory. Semiconductor memory finds its application in almost all the electronics fields comprises data sensing, monitoring and data storing operation. In computer, tablet, cell phones, real time data acquisition system, healthcare, military and many more. In most of these applications there are requirements of data sense, preserve and processing in real time operation. In other words, this selection of memories based on the types of data stored in semiconductor memory i.e. temporary or permanent in many demanding applications. But leakage current play vital role after data storage operation in semiconductor memories. Due to leakage current there may be chances of loss of information and it affects the system performance. Hence a leakage reduction technique proves to be an excellent alternative with memory circuit for minimized the leakage current.

This textbook for courses in Embedded Systems introduces students to necessary concepts, through a hands-on approach.LEARN BY EXAMPLE ¿ This book is designed to teach the material the way it is learned, through example. Every concept is supported by numerous programming examples that provide the reader with a step-by-step explanation for how and why the computer is doing what it is doing.LEARN BY DOING ¿ This book targets the Texas Instruments MSP430 microcontroller. This platform is a widely popular, low-cost embedded system that is used to illustrate each concept in the book. The book is designed for a reader that is at their computer with an MSP430FR2355 LaunchPadTM Development Kit plugged in so that each example can be coded and run as they learn.LEARN BOTH ASSEMBLY AND C ¿ The book teaches the basic operation of an embedded computer using assembly language so that the computer operation can be explored at a low-level. Once more complicated systems are introduced (i.e., timers, analog-to-digital converters, and serial interfaces), the book moves into the C programming language. Moving to C allows the learner to abstract the operation of the lower-level hardware and focus on understanding how to ¿make things work¿.BASED ON SOUND PEDAGOGY - This book is designed with learning outcomes and assessment at its core. Each section addresses a specific learning outcome that the student should be able to ¿dö after its completion. The concept checks and exercise problems provide a rich set of assessment tools to measure student performance on each outcome.
