Abstract
Differential programming of multiple resistive switching memory cells defining a bit is disclosed. The differential programming can mitigate invalid data values for the defined bit, referred to herein as an identifier bit. Embodiments of the present disclosure provide for detection of a program event(s) for a portion of resistive switching memory cells defining an identifier bit, and disconnecting a remainder of the memory cells from program supply voltage, prior to a duration of a program cycle. Additionally, the program cycle can be continued for the programmed memory cell(s) to facilitate a robust programming and enhance data longevity. The detection and subsequent disconnection can facilitate proper differential programming and mitigate unwanted program events that lead to invalid identifier bit results, as well as reducing power consumption for a program cycle of resistive switching memory.
