Abstract: A variety of applications can include one or more memory devices having user data preloaded for the application prior to reflowing the memory devices on the system platform of the application. A touch-up data refresh method can be implemented to gain read window budget and to improve retention slope to protect the preload content to tolerate reflow to the system platform. Techniques for data preload can include programming preload data into targeted blocks until the targeted blocks are programmed with the preload data and re-programming the preload data over the programmed preload data in the targeted blocks in a same set of memory cells, without an erase between programming and re-programming the preload data. Variations of such techniques can be used to prepare a memory device with preload data followed by performing a reflow of the memory device to a structure for an application to which the memory device is implemented.
