Abstract: A method and apparatus for providing a meshed power and signal bus system on an array type integrated circuit that minimizes the size of the circuit. In a departure from the art, through-holes for the mesh system are placed in the cell array, as well as the peripheral circuits. The power and signal buses of the mesh system run in both vertical and horizontal directions across the array such that all the vertical buses lie in one metal layer, and all the horizontal buses lie in another metal layer. The buses of one layer are connected to the appropriate bus(es) of the other layer using through-holes located in the array. Once connected, the buses extend to the appropriate sense amplifier drivers. The method and apparatus are facilitated by an improved subdecoder circuit implementing a hierarchical word line structure.

Abstract: A booting circuit, used during antifuse programming, that has a clamping circuit designed to prevent a programming voltage from being unnecessarily limited by other components in an integrated circuit. The booting circuit is connected between an external interface, such as a bond pad, and an internal line, and is activated when the programming voltage is being applied directly to the internal line (i.e., not through the external interface). When activated, the clamping circuit allows a suitable and sufficiently high voltage to be applied to the internal line to properly program the antifuses while also clamping the amount of voltage seen at the external interface.

Abstract: A reference circuit generates a reference voltage from a supply voltage. The reference circuit includes a current generating unit for generating generated currents. An output unit of the reference circuit generates the reference voltage based on the generated currents. A startup unit of the reference circuit allows the reference voltage to switch between different voltages levels in different modes.

Abstract: A circuit is designed with a decoder circuit (10), responsive to a first input signal (81) having a first voltage range, for producing a first output signal. An output circuit (11), responsive to the first output signal, produces a second output signal (26) having a second voltage range. The second voltage range includes a voltage less than a least voltage of the first voltage range and a voltage greater than a greatest voltage of the first voltage range.
