ABSTRACT:
A word oriented processing system includes a processing unit and a ferroelectric memory having a plurality of memory units organized in a matrix of rows and columns. Each memory unit stores a processor dataword of, for example, 8 or 16 bits, and contains a plurality of serial arrangements of, successively, a bitline connection, a first switching element, a ferroelectric capacitor and a node. The serial arrangements have the node in common. The node is connected to a plateline connection of the unit via second switching element. The processor reads or writes all bits of a word from one memory unit at a time. During reading or writing in one memory unit the first and second switching elements isolate the capacitors in other memory units from pulses on any of their plates.
