Abstract
A system and method for monitoring internal voltage sources in an integrated circuit, such as a DRAM integrated circuit, includes an internal analog multiplexing circuit, an internal analog-to-digital converter, and an interface circuit. Through the analog multiplexing circuit, the analog-to-digital converter sequentially connects to each voltage source and converts the measured voltage level of the source to a binary word. The interface circuit presents the binary word, e.g., serially, to test equipment off the integrated circuit.
