Abstract:
A controller includes an instruction table memory, a program counter, a first decoder, and a first executing unit. The instruction table memory stores an instruction code obtained by coding a sequence to access a nonvolatile semiconductor memory. A read address in the instruction table memory is set to the program counter. The first decoder decodes the instruction code read from the instruction table memory to output a first decode signal. The first executing unit executes access to the nonvolatile semiconductor memory on the basis of the first decode signal output from the first decoder.
