Abstract
An apparatus and method of reducing power consumption across a switch, such as an unprogrammed antifuse, is provided. The invention applies to antifuses, other switches such as transistor based switches, (e.g., FLASH, EEPROM and/or SRAM) and other devices exhibiting a leakage current, especially during a sleep or stand-by mode. During a sleep mode, such switches or other devices may be uncoupled from signals driving the switches, then terminals of each switch may be coupled to a common potential or allowed to float to a common potential thereby eliminating or reducing leakage currents through the switches.
