Abstract
A resistive memory sensing method includes sensing outputs of an offset-cancelling dual stage sensing circuit (OCDS-SC) by an NMOS offset-cancelling current latched sense amplifier circuit (NOC-CLSA). The NOC-CLSA is configured with a reduced input capacitance and a reduced offset voltage. Input transistors of the NOC-CLSA are coupled between latch circuitry and ground. A first phase output of the OCDS-SC is stored by the NOC-CLSA during a pre-charge step of the NOC-CLSA operation. A second phase output of the OCDS-SC is stored by the NOC-CLSA during an offset-cancelling step of the NOC-CLSA operation. By pipelining the OCDS-SC and NOC-CLSA, a sensing delay penalty of the OCDS-SC is overcome.
