Abstract: An integrated circuit (IC) includes both a field-programmable gate array (FPGA) and a hard array (HA). The FPGA includes a first set of functional groups that each include an underlying logic structure and memory cells for programming the underlying logic structure, a first set of routing buses, and a first set of routing interconnect areas that provide interconnections between the first set of functional groups and the first set of routing buses. The first set of routing interconnect areas includes transistors and memory cells for programming the interconnections. The HA includes a second set of functional groups that is equal in number to the first set of functional groups and that are arranged like the first set of functional groups. Each functional group in the second set of functional groups includes an underlying logic structure that is like the underlying logic structure of the first set of functional groups but which does not include memory cells for programming the underlying logic structure.

Abstract: An apparatus including a field-programmable gate array (FPGA) where the FPGA includes a plurality of X signal lines, a plurality of Y signal lines, and a plurality of memory cells. A first set of the memory cells are used to implement programmable interconnections between the X and Y signal lines and logic functions such as are implemented by configurable functional blocks, and a second set of the memory cells are not used to implement programmable interconnections between the X and Y signal lines or logic functions. Configuration data that is used to implement a specific configuration of the programmable interconnections between the X and Y signal lines and the logic function is stored in the first set of memory cells, and at least a portion of a validation number is stored in at least some of the second set of memory cells.

Abstract: A method of making an integrated circuit (IC) includes establishing an initial design for a field-programmable gate array (FPGA) to be included in the IC that includes programmable connections that can be programmed to implement a desired function; establishing an underlying physical template for the IC wherein at least a portion of the template is based on the initial design for the FPGA; selecting a specific configuration of the programmable connections in the FPGA; performing a manufacturing process of the IC using the underlying physical template, and, during the manufacturing process of the IC, bypassing selected on-state transistors in the FPGA used to implement the specific configuration of the programmable connections with metal connections while conserving the underlying physical template. An IC includes a semiconductor substrate and an FPGA fabricated on the semiconductor substrate.

Abstract: A data storage apparatus includes a latch having first and second storage nodes, a first pass transistor coupled to the first storage node, a row line coupled to a gate of the first pass transistor, and a row driver coupled to the row line. The row driver is configured to drive the row line to three different voltage levels. The three different voltage levels included a low logic level voltage, a full supply high voltage level, and a reduced high voltage level. The reduced high voltage level is greater than the low logic level voltage and less than the full supply high voltage level.
