Ferroelectric-based RAM sensing scheme including bit-line capacitance isolation

A ferroelectric memory includes a bit line for developing a signal coupled to a ferroelectric memory cell. An integrated load capacitor and sense amplifier are also coupled to the bit line. An isolation circuit is included for selectively electrically isolating the bit line load capacitor from the s...

Zusammenfassung:A ferroelectric memory includes a bit line for developing a signal coupled to a ferroelectric memory cell. An integrated load capacitor and sense amplifier are also coupled to the bit line. An isolation circuit is included for selectively electrically isolating the bit line load capacitor from the sense amplifier and ferroelectric memory cell during the active operation of the sense amplifier. The isolation circuit is compatible with both non-volatile ferroelectric and volatile dynamic memory operation.
