    Abstract: PROBLEM TO BE SOLVED: To improve reliability of a PLD. SOLUTION: A programmable electronic circuit is provided with at least one of a programmable interconnects, pass devices, a look-up table circuits and/or a multi-input logic circuits. Each of the programmable interconnects, the pass devices, the look-up table circuits, and/or the multi-input logic circuits has at least one or more dynamic threshold metal oxide semiconductor (DTMOS) transistors, full-depleted metal oxide semiconductor (FDMOS) transistors, partially depleted metal oxide semiconductor (PDMOS) transistors and/or double-gate metal oxide semiconductor transistor.

    Abstract: PROBLEM TO BE SOLVED: To reduce a cell area by providing a latch having an input for receiving a data signal and moreover an output, and connecting the latch selctively to a prescribed potential in response to a control signal. SOLUTION: A latch cell 6 consists of a driver inverter set 12 whose output of one side inverter is connected to the input of the other side inverter and a feedback inverter 14. On the other hand, a row selection pull-down transistor 22 and a data input line pull-down transistor 24 act as a switch, which connects the output node 18 of the latch cell 6 to a low voltage 26. Since the latch cell 6 is made to be flipped by connecting the cell to the ground in this manner, a short-channel CMOS transistor and a smaller NMOS transistor can be respectively used in a feedback inverter 14 and a pass gate transistor 4. Thus, the whole area of the cell is reduced, and effective and reliable operation of the cell is ensured.
