    摘要： Aspects for adjusting resistive memory write driver strength based on write error rate (WER) are disclosed. In one aspect, a write driver strength control circuit is provided to adjust a write current provided to a resistive memory based on a WER of the resistive memory. The write driver strength control circuit includes a tracking circuit configured to determine the WER of the resistive memory based on write operations performed on resistive memory elements. The write driver strength control circuit includes a write current calculator circuit configured to compare the WER to a target WER that represents the desired yield performance level of the resistive memory. A write current adjust circuit in the write driver strength control circuit is configured to adjust the write current based on this comparison. The write driver strength control circuit adjusts the write current to perform write operations while reducing write errors associated with breakdown voltage.

    摘要： Aspects disclosed in the detailed description include write driver circuits for resistive random access memory (RAM) arrays. In one aspect, a write driver circuit is provided to facilitate writing data into a resistive RAM array in a memory system. The write driver circuit is coupled to a selector circuit configured to select a memory bitcell(s) in the resistive RAM array for a write operation. An isolation circuit is provided in the write driver circuit to couple a current source to the selector circuit to provide a write voltage during the write operation and to isolate the current source from the selector circuit when the selector circuit is not engaged in the write operation. By isolating the selector circuit from the current source when the selector circuit is on standby, it is possible to reduce leakage current in the selector circuit, thus reducing standby power consumption in the memory system.
