Abstract
A circuit for selecting a select line from a plurality of first and second select lines is described. Each of an array of integrated circuit (IC) packages is coupled to (1) one of the first select lines and (2) at least one of the second select lines. The circuit includes a decoder for decoding a select data to select the select line, and circuitry for modifying the select data before the select data is applied to the decoder when each of the second select lines is not coupled to an IC device within each of the IC packages to ensure that the select line is not one of the second select lines. When each of the first and second select lines is coupled to an IC device within each of the IC packages, the circuitry for modifying does not modify the select data. A method for selecting a selected IC device within a selected IC package of an array of IC packages is also described.
