A 12 MHz, Sub Microamps Leakage and Low Active Power 64KB FRAM With Novel Design Techniques




Abstract: A 130nm 64KB low power Ferroelectric RAM is demonstrated which is designed for ultra low active power (less than 300uA @ 1Mhz) and fast access time (12Mhz). Using low leakage device, this 64KB FRAM has been able to achieve standby current under 5uA. Use of the low leakage device made meeting faster access times much more difficult, therefore a unique architecture and a distinct word line (WL) driver scheme is used to overcome the difficulty.
