    摘要: A method of performing a program-suspend-read operation in a PRAM device comprises programming a write block comprising N unit program blocks in response to a program operation request, and suspending the program operation after programming M unit program blocks, where M is less than N, in response to a read operation request. The method further comprises executing the requested read operation, and then resuming the programming of the write data block and programming (N−M) remaining unit program blocks.

    摘要: Embodiments of the invention provide devices or methods that include a status bit representing an inversion of stored data. New data is written to selected cells, the new data is selectively inverted, and the status bit is selectively toggled, based on a comparison between pre-existing data and new data associated with a write command. A benefit of embodiments of the invention is that fewer memory cells must be activated in many instances (when compared to conventional art approaches). Moreover, embodiments of the invention may also reduce the average amount of activation current required to write to variable resistive memory devices and other memory device types.
