The disclosed embodiments relate to a method and apparatus for identifying
short circuits in an integrated circuit device. The method may comprise
the acts of programming a first memory cell associated with a first digit
line to a first data value, programming a second memory cell associated
with a second digit line to a second data value, the second data value
being complementary with respect to the first data value, firing a first
sense amplifier associated with the first digit line, firing a second
sense amplifier associated with the second digit line after a time delay
with respect to the act of firing the first sense amplifier associated
with the first digit line, detecting a measured data value associated
with the second digit line, and comparing the measured data value to the
second data value to determine whether the first digit line is short
circuited to the second digit line. The apparatus may comprise a first
sense amplifier that is associated with a first digit line, a second
sense amplifier that is associated with a second digit line, and a
circuit that delays a firing operation of the second sense amplifier with
respect to a firing operation of the first sense amplifier to allow
detection of a short circuit between the first digit line and the second
digit line.
