Abstract
A memory circuit has a high voltage and low voltage supply nodes. One of a first and second sets of voltages is selectively applied to the supply nodes of the memory circuit in dependence upon memory operational mode. If in active read/write mode, then the first set of voltages is selectively applied. Conversely, if in standby no-read/no-write mode, then the second set of voltages is selectively applied. A low voltage in the second set of voltages is greater than a low voltage in the first set of voltages by a selected one of a plurality of low offset voltages, and a high voltage in the second set of voltages is less than a high voltage in the first set of voltages by a selected one of a plurality of high offset voltages. The offset voltages are provided by diode-based circuits that are selectively active. Selective activation is provided by either selectably blowable fuse elements or selectively activated switching elements.
