A ferroelectric memory comprises a plurality of memory cells and circuitry
to sense data thereof. Power supply decoupling circuitry may decouple
supplies of the memory device during a portion of reading data.
Additionally, ferroelectric domains of the memory cells may receive a
series of polarization reversals to improve domain alignment and
malleability. To drive reference cells of the memory with such
polarization reversals, a multiplexer may be configured to swap a data
bitline with a reference bitline so that reference cells may be accessed
as regular data cells. While reading a ferroelectric memory, a self-timer
circuit may monitor characteristics of the ferroelectric material and
adjust an integration duration for a sense amplifier based on the
monitored characteristics. A sampling-comparator may sample a signal
related to the ferroelectric material at one instant, which may then be
used subsequently thereafter by the self-timer circuit to influence an
integration duration of the sense amplifier.
