Abstract

A novel sensing scheme for high-density and high-speed sensing with a sub-10-μA cell current is presented. A source biasing method, which enhances the cell current drivability, and dynamic flip-flop sense amplifiers, in which a reference level is generated on the unselected bit lines with dummy cells, realize the high-speed and low-power operation. The potential of the dummy column is detected to control the sense amplifiers and decoders in a self-timed manner. Simulated results ensure the effectiveness of this sensing scheme for 5-V-only megabit flash E2PROMs (electrically erasable and programmable ROMs).
