Abstract

A stacked-substrate FPGA device is described in which a second substrate is stacked over a first substrate. Logic transistors (e.g., semiconductor devices and at least some conductive interconnections between them) are generally fabricated on (or over) a first substrate and memory transistors (e.g., SRAM cells and SRAM arrays) are generally fabricated on a second substrate over the first substrate. This has the effect of physically disposing elements of a CLB and a programmable switch on two different substrates. That is a first portion of a CLB and a programmable switch corresponding to logic transistors are on a first substrate and a second portion of these components of an FPGA corresponding to SRAM transistors is on a second substrate.
