Dual Sensing Current Latched Sense Amplifier

A method of sensing a differential between two bit lines, comprising:

• coupling a first bit line to a first output node of a sense amplifier and a second bit line to a second output node of the sense amplifier, in a first phase to supply an initial differential voltage to the sense amplifier;
• decoupling the first bit line from the first output node and the second bit line from the second output node during a second phase;
• and
• amplifying the initial differential voltage by discharging the first output node based on a voltage on the second bit line and the second output node based on a voltage on the first bit line, in the second phase.
