A modern, comprehensive introduction to DRAM for students and practicing chip designers Dynamic Random Access Memory (DRAM) technology has been one of the greatestdriving forces in the advancement of solid-state technology. With its ability to produce high product volumes and low pricing, it forces solid-state memory manufacturers to work aggressively to cut costs while maintaining, if not increasing, their market share. As a result, the state of the art continues to advance owing to the tremendous pressure to get more memory chips from each silicon wafer, primarily through process scaling and clever design. From a team of engineers working in memory circuit design, DRAM Circuit Design gives students and practicing chip designers an easy-to-follow, yet thorough, introductory treatment of the subject. Focusing on the chip designer rather than the end user, this volume offers expanded, up-to-date coverage of DRAM circuit design by presenting both standard and high-speed implementations. Additionally, it explores a range of topics: the DRAM array, peripheral circuitry, global circuitry and considerations, voltage converters, synchronization in DRAMs, data path design, and power delivery. Additionally, this up-to-date and comprehensive book features topics in high-speed design and architecture and the ever-increasing speed requirements of memory circuits. The only book that covers the breadth and scope of the subject under one cover, DRAM Circuit Design is an invaluable introduction for students in courses on memory circuit design or advanced digital courses in VLSI or CMOS circuit design. It also serves as an essential, one-stop resource for academics, researchers, and practicing engineers.

"DRAM Circuit Design" teaches readers the introductory level design of DRAM memory chips. It focuses on giving readers a reference that can be used to educate students or practicing design engineers in DRAM circuit design.

A systematic description of microelectronic device design. Topics range from the basics to low-power and ultralow-voltage designs, subthreshold current reduction, memory subsystem designs for modern DRAMs, and various on-chip supply-voltage conversion techniques. It also covers process and device issues as well as design issues relating to systems, circuits, devices and processes, such as signal-to-noise and redundancy.

The increasing demand for electronic devices for private and industrial purposes lead designers and researchers to explore new electronic devices and circuits that can perform several tasks efficiently with low IC area and low power consumption. In addition, the increasing demand for portable devices intensifies the call from industry to design sensor elements, an efficient storage cell, and large capacity memory elements. Several industry-related issues have also forced a redesign of basic electronic components for certain specific applications. The researchers, designers, and students working in the area of electronic devices, circuits, and materials sometimesneed standard examples with certain specifications. This breakthrough work presents this knowledge of standard electronic device and circuit design analysis, including advanced technologies and materials. This outstanding new volume presents the basic concepts and fundamentals behind devices, circuits, and systems. It is a valuable reference for the veteran engineer and a learning tool for the student, the practicing engineer, or an engineer from another field crossing over into electrical engineering. It is a must-have for any library.

Is your memory hierarchy stopping your microprocessor from performing at the high level it should be? Memory Systems: Cache, DRAM, Disk shows you how to resolve this problem. The book tells you everything you need to know about the logical design and operation, physical design and operation, performance characteristics and resulting design trade-offs, and the energy consumption of modern memory hierarchies. You learn how to to tackle the challenging optimization problems that result from the side-effects that can appear at any point in the entire hierarchy.As a result you will be able to design and emulate the entire memory hierarchy. Understand all levels of the system hierarchy -Xcache, DRAM, and disk. Evaluate the system-level effects of all design choices. Model performance and energy consumption for each component in the memory hierarchy.

This book pioneers the field of gain-cell embedded DRAM (GC-eDRAM) design for low-power VLSI systems-on-chip (SoCs). Novel GC-eDRAMs are specifically designed and optimized for a range of low-power VLSI SoCs, ranging from ultra-low power to power-aware high-performance applications. After a detailed review of prior-art GC-eDRAMs, an analytical retention time distribution model is introduced and validated by silicon measurements, which is key for low-power GC-eDRAM design. The book then investigates supply voltage scaling and near-threshold voltage (NTV) operation of a conventional gain cell (GC), before presenting novel GC circuit and assist techniques for NTV operation, including a 3-transistor full transmission-gate write port, reverse body biasing (RBB), and a replica technique for optimum refresh timing. Next, conventional GC bitcells are evaluated under aggressive technology and voltage scaling (down to the subthreshold domain), before novel bitcells for aggressively scaled CMOS nodes and soft-error tolerance as presented, including a 4-transistor GC with partial internal feedback and a 4-transistor GC with built-in redundancy.

The authors present readers with a compelling, one-stop, advanced system perspective on the intrinsic issues of digital system design.
