Abstract
Examples described herein provide a method for disabling a defective portion of a fabric die of a stacked IC device. The method includes receiving a signal indicating that a portion of a fabric die of a stacked IC device including at least two fabric dies is defective. The method further includes, in response to the signal, pulling a source voltage rail of the defective portion to ground, thereby disabling the portion, and operating the remainder of the fabric die without interference from or contention with the disabled portion. In one example, the stacked IC device is an active on active (AoA) device, and the portion of the fabric die includes a configuration memory cell. In one example, the signal is received after power-up of the stacked IC device.
