Flash Code with Block Deflation and Discrete Cell-Levels ○Michael Joseph Tan・Yuichi Kaji(NAIST) IT2014-2 |
抄録 |
(和) |
Several ideas are discussed for possible realization of a coding
scheme for flash memory that allow the operation of block deflation
while based on a discrete-cell model. Many flash codes have been
proposed so far but most of them assume that only two types
operations, cell programming and block erasure, are allowed for flash
memory. Another operation, block deflation, is recently attracting
interests of researchers, and new ideas including the rank-modulation
are eagerly studied. Those new ideas often assume that cell levels are
controllable with very precise detail, or flash cells take a
continuous value, which seems not realistic at this moment. The
purpose of this study is to discuss ideas that can be used to
construct a flash code that can utilizes block deflation within the
framework of discrete cell-level model. |
