Abstract:
A method includes writing received data sequentially to a particular location of a cyclic buffer of a memory device according to a first set of threshold voltage distributions. The method further includes performing a touch up operation on the particular location by adjusting the first set of threshold voltage distributions of the data to a second set of threshold voltage distributions in response to a determination that a trigger event has occurred. The second set of threshold voltage distributions can have a larger read window between adjacent threshold voltage distributions of the second set than that of the first set of threshold voltage distributions.
