Patent ID: 8885386

Claim:
A write driver in a sense amplifier for a resistive type memory, comprising: a cross-coupled latch including at least two latch transistors; a first output section including one or more first driving transistors coupled to a first differential output terminal, the one or more first driving transistors being configured to drive a first current through the first output section and not through the cross-coupled latch; and a second output section including one or more second driving transistors coupled to a second differential output terminal, the one or more second driving transistors being configured to drive a second current through the second output section and not through the cross-coupled latch wherein the first output section comprises: a PMOS type driving transistor from among the one or more first driving transistors, the PMOS type driving transistor being coupled to a first voltage potential and to the first differential output terminal; an NMOS type driving transistor from among the one or more first driving transistors, the NMOS type driving transistor being coupled to the first differential output terminal and to a second voltage potential; wherein the second output section comprises: a PMOS type driving transistor from among the one or more second driving transistors, the PMOS type driving transistor being coupled to the first voltage potential and to the second differential output terminal; and an NMOS type driving transistor from among the one or more second driving transistors, the NMOS type driving transistor being coupled to the second differential output terminal and to the second voltage potential.
