<p>A programming or function-setting cell for a field programmable gate array utilises ferroelectric capacitors connected to the nodes of a latch circuit to retain charge representing the state of the cell so that, following a power loss or a specific event upset, the programming information held by the latch circuit may be reinstated. The latch circuit comprises a pair of inverters having their inputs and outputs cross-coupled by way of respective switching transistors, and the capacitors are connected between the nodes and a common plate conductor normally held at a potential intermediate the supply potentials for the inverters. <IMAGE></p> |
