The goal of Ultra-Low Voltage Nano-Scale Memories is to provide a
detailed explanation of the state-of-the-art nanometer and sub-1-V
memory LSIs that are playing decisive roles in power conscious systems.
Emerging problems between the device, circuit, and system levels are
systematically discussed in terms of reliable high-speed operations of
memory cells and peripheral logic circuits. The effectiveness of
solutions at device and circuit levels is also described at length
through clarifying noise components in an array, and even essential
differences in ultra-low voltage operations between DRAMs and SRAMs.
Moreover, various kinds of on-chip voltage converters necessary to solve
the problems with internal power-supply managements are widely and
deeply discussed.
A lot of knowledge that authors have acquired to date, and circuits the
authors regard as important are covered from the basics to the
state-of-the-art. Thus, the book is beneficial to students and engineers
interested in ultra-low voltage nano-scale LSIs.
