Abstract: In one example, a nonvolatile memory device, such as a NAND flash memory device, includes an array of non-volatile memory cells. Program operations performed by the memory may be suspended (e.g., in order to service a high priority read request). The memory device includes a timer to track a duration of time the program operation is suspended. Upon program resume, the controller applies a program voltage after resume that is adjusted based on the duration of time the program operation is suspended.

Abstract: A memory device that has been programmed to store a single bit or multiple bits can perform a determination of a number of threshold voltages in one or more threshold voltage level regions. Based on the number of threshold voltages meeting or exceeding a threshold level, a page of bits can be read and if the bit error rate of the page of bits is below a threshold rate, the page of bits can be stored in the cells together with other bits stored in the cells and a provided additional page of bits. However, if the bit error rate of the page of bits is at or above the threshold rate, then the bit or bits stored in the cells can be error corrected and stored together with a provided additional page of bits.

Subsequently, an operation related to data stored in the memory component can be performed based on the attribute.
