ABSTRACT:
A data path including a local input/output (LIO) line and a global input/output (GIO) line coupled together through an input/output (IO) line coupling circuit. The coupling circuit is coupled to an internal voltage supply, and couples and decouples signal lines of the GIO line from the supply terminal according to read data coupled to the LIO line. The GIO line is coupled to a current sense amplifier to generate output voltage signals that are coupled to an output buffer. An example of a current sense amplifier coupled to the GIO line includes first and second load circuits and first and second n-channel MOS (NMOS) transistors coupled to a respective load circuit. The gates of NMOS transistors are cross coupled, and input current signals are coupled to source terminals of the NMOS transistors and the output voltage signals are coupled from the drain terminals of the NMOS transistors.
