Combining Flash Codes for Write Deficiency Reduction

초록

영어

Flash codes are designed to write and read information from a flash memory device. The performance of a flash code is often described in terms of write deficiency. Flash codes with low write deficiencies help lengthen the lifespan of flash devices. This paper describes a technique for combining the Index-less Indexed Flash Code (ILIFC) and the Layered Index-less Indexed Flash Code (LILIFC) in order to decrease the write deficiency. Two resulting flash codes are proposed: the Bi-Modal Flash Code (BMFC) and the Two-Split Bi-Modal Flash Code (BMFC2). These proposed flash codes have an asymptotic worst case write deficiency of O(k2q + n/k), and through computer simulation are shown to have significantly lower average write deficiency compared with the ILIFC and LILIFC.
