Abstract:
Example embodiments include a level shifting write driver in a sense amplifier for a resistive type memory. The write driver may include a cross-coupled latch circuit, a first output section, a second output section, and an input section. The first output section includes one or more first driving transistors to drive a first current through the first output section and not through the cross-coupled latch. The second output section includes one or more second driving transistors configured to drive a second current through the second output section and not through the cross-coupled latch. The current flows of the outputs sections are isolated from the latch circuit. In some embodiments, no two PMOS type transistors are serially connected, thereby reducing the consumption of die area. In some embodiments, a single control signal is used to operate the write driver.
