Estimating the term…
A basic cell circuit architecture having plurality of cells with fixed transistors configurable for the formation of logic devices and single and dual port memory devices within a structured ASIC is provided. Different configurations of ensuing integrated circuits are achieved by forming variable interconnect layers above the fixed structures. The circuit architecture can achieve interconnection of transistors within a single cell or across multiple cells. The interconnection can be configured to form basic logic gates as well as more complex digital and analog subsystems. In addition, each cell contains a layout of transistors that can be variably coupled to achieve a memory device, such as a SRAM device. By having the capability of forming a logic circuit element, a memory device, or both, the circuit architecture is both memory-centric and logic-centric, and more fully adaptable to modern-day SoCs.
A circuit architecture comprising an arrangement of transistors configured for formation of at least one of logic circuitry and memory circuitry depending upon a layout of variable overlying layers, wherein the arrangement of transistors comprises:
