Description

technical field [0001] The invention discloses a simulation platform, relates to the technical field of NandFlash storage, in particular to a NandFlash wear balance simulation platform. Background technique [0002] With the rapid development of computer technology, people pay more and more attention to data storage. New storage media such as Nand flash memory are playing an increasingly important role in the field of modern data storage because of their low cost, high storage density, and low power consumption. Among them, NandFlash memory is a kind of flash memory. It adopts nonlinear macro-cell mode internally, which provides a cheap and effective solution for the realization of solid-state large-capacity memory. NandFlash is suitable for the storage of large amounts of data, so it has been more and more widely used in the industry, such as embedded products including digital cameras, MP3 player memory cards, small and exquisite U disks, etc. However, as a loss device, ...
