Abstract
An error-correcting memory system includes a storage module which receives an address and which reads data bits and check bits at the address, and it further includes a zero DC power gate array which corrects errors in the data bits by decoding multiple minterms from the check bits; wherein the gate array is comprised of: a plurality of capacitors, one for each of the minterms; a control circuit for generating a control signal that is in one state when the minterms are to be detected and is otherwise in an opposite state; a charging circuit, coupled between the control circuit and the capacitors, for charging all of the capacitors only when the control signal is in its opposite state; and a discharging circuit, coupled between the control circuit and the capacitors, for indicating the presence of the minterms by selectively discharging the capacitors as a selectable decode of the check bits only when the control signal is in its one state.
