Abstract
An apparatus includes a memory and a controller. The memory includes a plurality of memory devices. Each memory device has a plurality of page types. The plurality of page types are classified based on error rate variations. The controller may be configured to write user data and error-correction data to the memory. The user data and the error-correction data are organized as a super-page. The super-page includes a plurality of sub-pages. The plurality of sub-pages are written across the plurality of memory devices such that the plurality of sub-pages are stored using more than one of the plurality of page types.
