Abstract
A data storage and replay device uses measurements of the evolution of performance of the storage medium (typically a flash memory circuit) to predict an error rate of retrieval from a region of the storage medium. The prediction is used as a basis for dynamically selecting an ECC for encoding the data prior to storage of the data. The ECC is selected from a plurality of available ECC's so that a fastest encodable ECC is selected that is predicted to produce no more than a predetermined post-decoding error rate given the information. On decoding the data, which is typically audio or video data, is decoded and replayed at a predetermined speed. In another embodiment, the data stored using a plurality of ECC's together and an ECC is selected dynamically for decoding, so that an output data rate can be maximized or power consumption on replay can be minimized.
