Title:
Coding and Bounds for Partially Defect Memory Cells 
Pages contribution:
Extended Abstract - 2 pages 
Abstract:
This paper considers coding for partially stuck memory cells. Such memory cells can only store partial information as some of their levels cannot be used due to, e.g., wear out. First, we present a code construction for masking such partially stuck cells while additionally correcting errors. Second, we derive a sphere-packing and a Gilbert-Varshamov bound for codes that can mask a certain number of partially stuck cells and correct errors additionally. A numerical comparison between the new boun...    »
