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 retreival. 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.

Claim (Index 11):
A memory controller for use with a memory device, comprising:\n a processor configured to\n compare first and second frames of an input data stream to identify a matching portion; \n store the first frame at first physical addresses within the memory device while including the matching portion; \n store the second frame at second physical addresses within the memory device while excluding the matching portion; \n store a link between the second frame and the matching portion of the first frame; and \n read the second frame from the memory device while using the link to obtain the matching portion that was excluded during storage of the second frame but was included during storage of the first frame.
