Abstract:
A programmable integrated circuit, comprising:a plurality of macrocells disposed in a column, each of the macrocells having a first logic module and a second logic module;a plurality of programming conductors, each respective one of the programming conductors extending parallel to one another in a first dimension between the first and second logic modules of each macrocell of the column,wherein each of the macrocells further comprises: a first programming transistor and a second programming transistor, a first wire segment extending in a second dimension perpendicular to the first dimension from an input of the first logic module of the macrocell to a first electrode of the first programming transistor, a second wire segment extending in the second dimension from an input of the second logic module of the macrocell to a first electrode of the second programming transistor, one of the plurality of programming conductors being coupled to a second electrode of the first programming transistor and to a second electrode of the second programming transistor, a gate electrode of the first programming transistor not being coupled to a gate electrode of the second programming transistor, wherein a programming current can flow in the first dimension through the one programming conductor and then flow to the first transistor or to the second transistor without passing through any antifuse.
