Patent ID: 7277310

Claim:
A plurality of sense amplifiers, comprising: a first sense amplifier coupled to a first pair of digit lines, the first pair of digit lines having a first and second digit line; a second sense amplifier coupled to second pair of digit lines, the second pair of digit lines having a first and second digit line; a common reference line; a first switch having a first node coupled to the first digit line of the first pair of digit lines and a second node coupled to the common reference line, the first switch further having a control node and configured to couple the first node to the second node in response to a first control signal coupled to the control node of the first switch; a second switch having a first node coupled to the first digit line of the second pair of digit lines and a second node coupled to the common reference line, the second switch further having a control node and configured to couple the first node to the second node in response to a second control signal coupled to the control node of the second switch; and control logic coupled to the first and second sense amplifiers and further coupled to the control nodes of the first and second switches, the control logic configured to control the second sense amplifier to drive the first digit line of the second pair of digit lines to a voltage level and generate active first and second control signals for the first and second switches to couple the first digit line of the first pair of digit lines to the first digit line of the second pair of digit lines.
