ABSTRACT:
A nonvolatile memory apparatus includes a separate controller circuit and memory circuit. The controller circuit is fabricated on a first integrated circuit chip. The controller circuit includes a plurality of charge pump circuits, a system interface logic circuit, a memory control logic circuit, and one or more analog circuits. The memory circuit is fabricated on a second integrated circuit chip and includes a column decoder, a row decoder, a control register, and a data register. A memory-controller interface area includes a first plurality of die bond pads on the first integrated circuit chip and a second plurality of die bond pads on the second integrated circuit chip such that the first and second integrated circuit chips may be die-bonded together. A single controller circuit may interface with a plurality of memory circuits, thus further reducing overall costs as each memory circuit does not require a dedicated controller circuit.
