Abstract: The present disclosure, in various embodiments, describes technologies and techniques for use by a memory controller or similar device for storing sequential image data or other data streams composed of pages of data. In one example, the memory controller compares data within current and previous image frames on a page-by-page basis. If a pair of pages match, the memory controller creates a link between the two pages so the duplicate page need not be stored. During a subsequent read operation, the flash controller accesses stored links to identify the physical storage addresses of any matching pages stored in connection with a previous frame to permit efficient retrieval. In some examples, a page is compared with both the previous corresponding page and with the neighboring pages of that previous page. Exemplary read, write and erase operations are described herein using the links.
