Non-volatile memory accelerator and method for speed up data accessing thereof

A non-volatile memory accelerator and a method for speed up data accessing thereof are provided. The non-volatile memory accelerator includes a data pre-fetch unit, a cache unit, and an accessing interface circuit. The data pre-fetch unit has a plurality of line buffers, provides a read data from one of the line buffers according to a read command, or reads at least one cache data to be the read data according to the read command. The data pre-fetch unit further stores a plurality of pre-storing data with continuous addresses according to the read command. The cache unit stores the at least one cache data and the pre-storing data with continuous addresses. The accessing interface circuit is used to be an interface circuit of the non-volatile memory.
