© 2015 IEEE. Secure Write-Efficient Memory (WEM) was proposed in  to solve the endurance and the insecure deletion problems in flash memories. Information theoretical results, i.e., the achievable region and the secrecy rewriting capacity, have been obtained. In this work, a code construction for secure WEM is presented and it is optimal for a large family of secure WEM.
