Abstract:
Memory devices may employ flip-flops with paired transistors in sense amplifying circuitry to sense charges stored in memory cells. Paired transistors may present mismatches in electrical characteristics, which may affect the sensitivity of the sense amplifying circuitry. Embodiments include systems and methods that compensate and/or mitigate mismatches in the electrical characteristics of the paired transistors. To that end, the memory devices may sense the mismatches during a compensation period and pre-compensate the read-out of data lines to improve the sensibility of the sense amplifying circuitry.
