A ferroelectric integrated circuit memory device includes: a plurality of memory cells, each including a ferroelectric material, a plurality of conducting lines, each connected to or connectable to a selected one of the memory cells; a drive circuit for applying a predetermined voltage for a predetermined time to a selected one of the conducting lines, the predetermined voltage and time being the normal voltage and time required to perform write or read functions to the memory cell, a function selected from the group of: writing a logic state to the selected memory cell, and reading the selected memory cell; and a mode control circuit responsive to an external signal for adjusting the predetermined voltage or the predetermined time to perform an operation selected from the group consisting of: a partial read of the selected memory cell, and a partial write of the selected memory cell; and applying ferroelectric stress to the memory cell. A known logic state is written to the memory cells, the cells are heated, and then read to provide output data indicative of the likelihood of premature failure for each of the memory cells. Ferroelectric stress is applied to the cells either before or after the cells are written to by repeatedly applying a voltage to the cells corresponding to a logic state opposite that of the written logic state.

A ferroelectric field effect transistor (FET) has a gate, source, drain, and substrate. A negative voltage is applied to the gate. Ground potential is applied to the source, drain, and substrate. The negative voltage has a magnitude at least equal to the coercive voltage of the FET. A positive voltage is then applied to the gate. Ground potential is applied to the source and substrate. The positive voltage is no less than the coercive voltage. Either a positive voltage or a ground potential is applied to the drain to write a logic state to the FET. A voltage is applied to the gate. Ground potential is applied to the source. A positive voltage is applied to the drain. The drain current is measured and compared to a compare current. The relative size of the drain current compared to the compare current is indicative of the stored logic state in the FET.

A semiconductor layout design analyzer alerts a user of areas in a semiconductor layout design that may be candidates for radiation induced inversion. The analyzer includes means for gathering information, means for identifying, and means for alerting the user. The means for gathering gathers, from the layout design, placement information for thick oxide, low-doped p-type single crystal silicon, and n-type silicon. The means for identifying identifies, in the layout design, thick oxide overlaying low-doped p-type single crystal silicon and abutting n-type silicon. The means for alerting the user alerts the user of the identified areas of thick oxide.

The external event detection device comprises an electronic unit () and an external event sensor (), the electronic unit having at least a non-volatile memory cell (, T) in which data relative to at least one external event detected by the external event sensor can be stored. According to the invention, the external event sensor defines an energy harvester that transforms energy from said at least one external event into electrical energy contained in an electrical stimulus pulse provided to the electronic unit. The electronic unit is arranged for storing said data by using only the electrical energy contained in the electrical stimulus pulse. In particular, the non-volatile memory cell is directly set to its written logical state from its initial logical state by the electrical stimulus pulse provided by said energy harvester. In a preferred embodiment, the electronic unit further comprises a set circuit () comprising a second FET transistor (T) arranged between the ground of the electronic unit and the drain of a first FET transistor (T) defining the non-volatile memory cell, this switch having a control gate connected to the control gate of the first FET transistor. The second FET transistor is turned on when an electrical stimulus pulse is provided to the electronic unit, connecting the drain (DRN) of the first FET transistor (T) to ground and thus allowing the secure setting of the non-volatile memory cell.
