Compact ReRAM based FPGA
Abstract:
A push-pull resistive random access memory cell circuit includes an output node, a word line, a first bit line, and a second bit line. A first resistive random access memory device is connected between the first bit line and the output node and a second resistive random access memory device is connected between the output node and the second bit line. A first programming transistor has a gate connected to the word line, a drain connected to the output node, and a source. A second programming transistor has a gate connected to the word line, a drain connected to the source of the first programming transistor, and a source. The first and second programming transistors have the same pitch, the same channel length, and the same gate dielectric thickness, the gate dielectric thickness chosen to withstand programming and erase potentials encountered during operation of the push-pull ReRAM cell circuit.
