Abstract :
A precision high voltage wave-shaper is demonstrated in 0.18μm 64-256Meg NOR SSI flash MLC memory chip to demonstrate feasibility of a ∼8bit accuracy HV delivering system for 1.8V multi giga bit (>4 Gbit) density 4bits/cell multilevel memory. Dynamic adaptive HV bias scheme (DYAHV) and unique nested array driving loop shown for the first time in this work.
