Multi-product die configurable as two or more programmable integrated circuits of different logic capacities

摘要

A multi-product integrated circuit die includes at least two different portions, of which at least one portion can be deliberately rendered non-operational in some manner (e.g., non-functional, inaccessible, and/or non-programmable) within the package. A selection code storage circuit stores a product selection code. A first value of the product selection code selects the option where both the first and second portions of the first die are operational. A second value of the product selection code selects the option where only the first portion of the first die is operational. The selection code storage circuit can include non-volatile memory or a fuse structure, or the product selection code can be configured as a package bonding option. The product selection code can also enable boundary scan for the operational portion of the die, and omit from the boundary scan chain any portions of the die that are deliberately rendered non-operational.
