Implantable medical grafts fabricated of metallic or pseudometallic films of biocompatible materials having a plurality of microperforations passing through the film in a pattern that imparts fabric-like qualities to the graft or permits the geometric deformation of the graft. A write function may be written to a shared memory device and designated as a virtual EEPROM driver. The wire impedances between the data lines and the pixel array are thus made the same.
