    Abstract: Examples herein include techniques for flash page retirement following one or more defects in nonvolatile memory. In some examples, a storage controller may retire a first logical page in response to a first read error, and write data to the one or more NMV devices in a program-erase (P/E) cycle without a dummy page being programmed or generated for the retired first logical page. The storage controller may further retire a second logical page in response to a second read error, wherein the first logical page has a higher order than the second logical page in a same physical memory page.
