MEMORY SUPPORT PROVIDED WITH MEMORY ELEMENTS OF FERROELECTRIC MATERIAL AND NON-DESTRUCTIVE READING METHOD THEREOF

摘要

A method for non-destructive reading of logic data stored in a memory includes applying to a first wordline a reading voltage so as not to cause a variation of the stable state of polarization of a layer of ferroelectric material, and generating a difference of potential between first and second bitlines. An output current is generated comparing the output current with a plurality of comparison values, and determining the logic value of the logic data to be read on the basis of the comparison.
