A new serial sensing approach for multistorage non-volatile memories

Abstract

This paper presents a novel serial sensing method for multistorage non-volatile memories. The method is based on a dichotomic algorithm to detect the level stored in the memory cell selected. While maintaining the main advantage of the serial approach (the use of a single sense amplifier), the method proposed also reduces to a minimum the overall time needed to read the cell content. Sensing time is independent of the memory cell content.
