Abstract: The present technology is directed to a method for accessing a memory device in response to read requests is described. The method comprises, in response to a first request, composing a first read sequence using a command protocol of the memory device. The first read sequence includes a command code and a starting physical address. Upon receipt of a second request, the method determines a starting physical address of a second read sequence according to the command protocol of the memory device. If the starting physical address of the second read sequence is sequential to an ending physical address of the first read sequence, then the method composes the second read sequence using the command protocol without a command code, else the method composes the second read sequence using the command protocol with a read command.
