Abstract :
We consider t-write codes for write-once memories with cells that can store multiple levels. Using worst-case sum-rate optimal 2-cell t-write code constructions for the asymptotic case of continuous levels, we derive 2-cell t-write code constructions that give good sum-rates for cells that support q discrete levels. A general encoding scheme for q-level 2-cell t-write codes is provided.
