    摘要: A ferroelectric destructive read-out memory system includes a power source, a memory array including a memory cell, and a logic circuit for applying a signal to the memory array. Whenever a low power condition is detected in said power source, a disturb prevent circuit prevents unintended voltages due to the low power condition from disturbing the memory cell. The disturb prevent circuit also stops the operation of the logic circuit for a time sufficient to permit a rewrite cycle to be completed, thereby preventing loss of the data being rewritten.

    摘要: A ferroelectric integrated circuit memory includes a memory cell having a ferroelectric capacitor, one electrode of which is connected to a bit line through a transistor, and the other electrode of which is connected to a plate line. The bit line is also connected to system ground through a precharge transistor. In a read cycle, the precharge transistor remains on after the word line goes high connecting the capacitor to the bit line. At least a portion of the linear displacement current that flows to the bit line is drained off to ground via the precharge transistor, thereby increasing the switching voltage across the ferroelectric capacitor. The precharge transistor is turned off before or during the switching of the ferroelectric capacitor. The signal applied to the gate of the precharge transistor is boosted above the supply voltage of the memory to shorten the cycle time.

    摘要: 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.

    摘要: A timing circuit produces a clock signal. An address buffer circuit receives and stores a first address in a first latch and a second address in a second latch asynchronously with respect to the clock signal. A memory control circuit associated with an array of memory cells accesses a first memory cell in the array corresponding to the first address in a first clocked access cycle, and accesses a second memory cell in the array corresponding to the second address in a second clocked access cycle. If a further address is asynchronously received before said second access cycle, the further address replaces the second address in the second latch.

    摘要: The invented technique permits the gate length to equal the channel length: source/drain regions are self-aligned and non-overlapping with respect to their gate electrode. The non-overlapping feature, along with other optimized device characteristics, are generally provided by defining a gate electrode over a substrate, forming an implant mask of dielectric, for example, on the sides of the gate electrode, and implanting a source/drain region such that the implant mask shields a portion of the substrate from implantation to provide a gap between a side edge of the gate electrode and the implanted regions. The source/drain region is then heat driven until its side edge is substantially aligned with the edge of the gate electrode. Self-aligned source/drain contacts are also provided using the implant mask to isolate the gate electrode from the contacts and interconnects.

    摘要: An electrical circuit is formed by forming and patterning a conductive layer on a substrate, forming and patterning a conductive layer on another substrate, depositing a dielectric layer on at least a portion of one of conductive layers, mounting an integrated circuit (IC) between the substrates, coupling the IC to the conductive layers, and affixing the substrates together with the conductive layers between the substrates. These are either separate substrates or a unitary substrate. The IC is mounted either to a substrate, a conductive layer, or a dielectric layer. The IC is coupled to the conductive layers either directly or through openings formed in the dielectric layer. An interior conductive layer may be used to couple the IC to the conductive layers.
