Abstract (in Japanese) (See Japanese page) 
(in English) Floating codes aim to store rewritable data in irreversible memories
like flash memories, whose value can only transit from the lower to the
higher unless a complex operation. Recently, we proposed a floating code
construction using so-called ``coset coding'' teqchnique with Hamming
code. And we showed that our construction using (7,4) Hamming Codes
guarantees much rewrites and achieves an upper bound, and we also
proposed a conjecture about the performance of our construction using
general Hamming Codes. In this report, we discuss and verify the
conjecture in some parameters.
