Abstract: Improved differential programming of multiple two-terminal memory cells that define an identifier bit is provided. A differential circuit can be defined by a plurality of resistive memory cells connected to a single bitline of an array, with respective wordlines coupling second terminals of the memory cells to ground (or low voltage). Some disclosed circuits can provide very rapid intrinsic suppression of a non-programmed memory cell(s) defining an identifier bit in response to programming of another memory cell (or group of cells) defining the identifier bit. Disclosed differential programming can reduce power consumption and mitigate or avoid invalid data results for an identifier bit.

Abstract: Improved differential programming of multiple two-terminal memory cells that define an identifier bit is provided. Differential programming can apply a program cycle to multiple memory cells concurrently, detect a program event for one (or a first group) of the memory cells and disconnect all of the memory cells from a program supply voltage in response to detecting the program event. Moreover, disconnecting the memory cells can be accomplished prior to a duration of the program cycle, serving to mitigate an invalid data result for the identifier bit, as well as reduce power consumption associated with the differential programming. Some disclosed circuits can provide intrinsic suppression of a non-programmed memory cell(s) defining an identifier bit in response to programming of another memory cell (or group of cells) defining the identifier bit. Disclosed differential programming can reduce power consumption and mitigate or avoid invalid data results for an identifier bit.
