Abstract
A replaceable printer component having an integral memory for use in a printing system includes a semiconductor die and a plurality of circuits formed on the semiconductor die. Each circuit is associated with and indicates the state of a bit in the memory. The memory stores a plurality of functional bits that must match values expected by the printing system for proper operation of the printing system. The memory stores a plurality of informational bits that are not critical to proper operation of the printing system. A large percentage of the circuits associated with the functional bits are positioned substantially near a center of the semiconductor die.
